I learned in this lesson we talked about the heavenly bodies which is comets, asteroids, and meteorids. Comets, asteroids, and meteoroids are all put together in this lesson because they are all fundamentally the same thing: little chunks of rock and/or ice that aren't part of a big planet. Metals and rocky material make up asteroids, while ice, dust, and rocky material make up comets. Asteroids and comets both formed early in the solar system's history, around 4.5 billion years ago.

From today's lesson, we tackled about the different heavenly bodies which composed of comets, asteroid and meteoroid. Comets are a cosmic snowballs of frozen gases, rock and dust that orbit the sun. There are likely billions of comets orbiting our sun in the kuiper belt and even more distant oort cloud. Asteroid are metallic or rocky bodies without atmosphere that are too small to be classified as planets. While the meteoroid is the small rocky body in. The outer space and smaller that asteroid.

In this lesson I learned a lot of things about heavenly bodies, their structure compositions and importance. How they work in different ways , How they differ from each other and what is their purpose especially the meteoroids, asteroids, and comets.

And the importance of heavenly bodies such as meteoroids, meteorites, comets, and asteroids is that ,It aids in the discussion of major issues. It studies the birth and development of the universe, as well as the evolution, physics, chemistry, meteorology, and motion of celestial objects. We may learn about our origins, our future, and how physics works in situations that are hard to replicate on Earth by researching the cosmos beyond our own planet. Humans have looked to the sky for guidance in navigating huge oceans, determining when to produce crops, and answering concerns about our origins and how we arrived here throughout history. It's a practice that can change the way we see the world by opening our eyes, giving us context for our place in the universe. As our knowledge of the world grows, we find ourselves and our perspective of the world becoming increasingly interwoven with the stars. The discovery that the basic components found in stars, as well as the gas and dust that surrounds them, are the same elements that make up our bodies has strengthened our bond with the universe. This connection has an impact on our lives, and the wonder it evokes is likely one of the reasons why astronomy's magnificent visuals are so popular in today's culture.

Comets are made up of mostly ice and dust and are known for the tail of gas and dust that gets blown away from them when they’re near the sun. Some, like asteroids, orbit the sun and come around in regular intervals.
Meteoroids are the somewhat small, rocky or metal-based objects flying around space, typically unseen except with sophisticated equipment. They are often fragments of asteroids or comets.
Mateors are the meteoroids that enter Earth’s atmosphere, where they often burn up meaning they can often be seen with the naked eye. This is what we sometimes call a shooting star. When there are a lot of them at once, we call it a meteor shower.
Meteorites are the meteoroids that have made it all the way to Earth’s surface.
Asteroids are rocky objects that vary in size, but on average they’re between the size of a meteoroid and a planet. Asteroids are mostly found within the asteroid belt between Mars and Jupiter.

Comets are frozen remnants of the solar system's origin, made up of dust, rock, and ices. They can be a few miles to tens of miles across, but when they get closer to the Sun, they heat up and spew gases and dust into a luminous head the size of a planet.

Small stony objects orbiting the Sun are known as asteroids. Asteroids orbit the Sun in the same way that planets do, but they are considerably smaller. Small stony objects that orbit the sun are known as asteroids. Although asteroids orbit the sun in the same way as planets, they are much smaller.

Meteoroids are small asteroids to large asteroids that float across space. Meteors are fireballs or "shooting stars" that enter Earth's atmosphere (or that of another planet, such as Mars) at great speeds and burn up.

A meteor is a bright streak in the sky created by a meteoroid crashing through the atmosphere of Earth. Meteoroids are rocky or iron-based objects that orbit the sun. Asteroid collisions produce the majority of meteoroids, which are tiny rock pieces. As they orbit the sun, comets produce meteoroids, which are dust and debris that fall to Earth.

A meteorite is a rock that falls from space to Earth. Asteroids, tiny stony rocks that orbit the Sun principally between Mars and Jupiter, make up the great bulk of meteorites.

What I have learned from today's lesson?

In today's lesson, I learned many things about the heavenly bodies that can be found in our solar system. Specifically, comets, asteroids, meteoroids, meteors, and meteorites.

COMETS- are heavenly bodies like dirty snowballs in which they are composed of dust and metal rocks and are surrounded by a thick icy shell. These types of heavenly bodies come from two places in the solar system: ¹ Kuiper belt which is the origin of many short-period comets in the solar system, and the other one is the ² Oort cloud which is the origin of the long period comets in our solar system. In addition to this, comets orbit the Sun in a highly elliptical orbit.
Halley's Comet is the most famous comet. This comet was last seen in February 1876.
Parts of comets:

1. Nucleus

2. Coma

3. Ion tail

4. Dust tail

ASTEROIDS- the second heavenly body discussed earlier—are rocky objects smaller than planets that were left over from the formation of our solar system. They are also known as "minor planets." These are made mostly of rock, with some clay, silicate, and different metals (nickel and iron). Most asteroids are located in the main asteroid belt.
Trojan Asteroid - shares Jupiter orbital path.
Near Earth Asteroid - have orbits that pass close by the Earth.
Three broad composition classes of asteroids:

1. C-type (chondrite)- most common asteroid. Consist of silicate rocks and clay.

2. S-type (stony)- made up of nickel-iron, and silicate materials.

3. M-type (metallic)- made up of nickel-iron.

METEOROIDS - these heavenly bodies are the rocky or metallic fragments of the planets, asteroids, and comets that have not yet entered the Earth's atmosphere.

METEORS - are commonly known as "shooting stars." If meteoroids were heavenly bodies that didn't enter the Earth's atmosphere, but meteors would, because these are the meteoroids that heat up in the atmosphere, which later form light that can be seen by our naked eye.

METEORITES - these are the heavenly bodies that have already reached the Earth's surface.

Today lesson, I've learned alot about the Comets, Asteroids, and the Meteoroids, Meteors, and Meteorites.
This are the heavenly body in our solar system.

Comets is icy object that releases a gases it orbits the sun. frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide. While
Asteroids are small and rocky objects that orbit the Sun. Asteroids orbit the Sun like planets, they are much smaller than planets. There are lots of asteroids in our solar system. Most of them are located in the main asteroid belt, a region between the orbits of Mars and Jupiter and some asteroids go in front of and behind Jupiter. These are called Trojan asteroids.

Meteorides is the Is the metallic or rocky of a asteroid planet or comet.
Meteors is also called the shooting stars, it also a streak of lights and the Meteorites is a meteor that reaches the earth's surface.

# data[].attributes.body
For today's lesson, I have learned the difference between the Comets and Asteroid and their exact location as well are the differences between Meteors, Meteorite and Meteoroid.

Comets are dust, rock, and ice remnants from the birth of the solar system. They range in size from a few miles to tens of miles across, but as they get closer to the Sun, they heat up and spew gases and dust into a luminous head the size of a planet.
Perhaps the most famous comet in history is Halley's Comet. Halley's comet may be the only comet visible to the naked eye that appears twice in a human lifetime. The last time that happened was in 1986.

Asteroids are tiny rocky bodies orbiting the Sun. Asteroids orbit the Sun like planets, but they are considerably smaller. Asteroids abound in our solar system.  In our solar system, there are several asteroids. The majority of them are in the main asteroid belt, which lies between Mars and Jupiter's orbits. Some asteroids pass in front of Jupiter and others pass behind it.
The Jupiter trojans, often known as trojan asteroids or just trojans, are a vast group of asteroids that circle the Sun alongside Jupiter.

The major distinction between asteroids and comets is their composition, as in, what they are made of. Metals and rocky material make up asteroids, while ice, dust, and rocky material make up comets. Asteroids and comets both created some 4.5 billion years ago, early in the solar system's history.

METEOROIDS, METEORS, METEORITES

Meteoroids are rocky or metallic pieces of debris that move through space, some of which are aimed for Earth.

Meteors are meteors that burn up in the Earth's atmosphere when you see a meteor shower in the sky. We commonly refer to meteors as "shooting stars" during a meteor shower.

Meteorites are something that we all can see because they are the ones that crash down to Earth.

It turns out that their location is crucial:
Meteoroids are well above the horizon.
When meteors break down in the atmosphere, they leave streaks of light as they fall to Earth.
As a result, they begin their journey as a meteoroid in the sky. Then they come crashing down like a meteor. When it lands on Earth, we refer to it as a meteorite.

Today I learned a lot of things on comets, asteroid and meteoroid. Comets is like a dirty snowballs which is composed of dust, rock and ice that orbit in Sun. While Asteroid are rocky body smaller or sometimes called minor planets, it composed of dust, rock and metal that orbiting in Sun between Mars and Jupiter within the main asteroid belt.
Shooting star that we usually see are not meteor already but firstly it is meteoroid and then become meteors. Just like other object meteoroid have a process. Meteoroids are small asteroids which can we think as "space rocks". They are in top of Earth's atmosphere. And when meteoroids enter on our atmosphere the fireballs we called as "shooting star", we wish on it to become true and that is the Meteors. Moving forward when meteor are now down at land of the Earth it is called Meteorites which is typically range between the size of "pebble".

Today's topic is all about the different heavenly bodies that is term used in different matter in the universe. But today we only focus about the differences of meteor, meteorite and meteoroid.
• Meteor is the streak of light that can be seen in the sky usually when a small piece of cometary material enters the atmosphere. But mostly, meteor are also called as a shooting star.
• Meteorites is a small, rocky bodies that cause the lights. It is a rock that falls to Earth from space. But some of the meteorites are pieces of asteroids.
• Meteoroids is far up in our sky, it is a stony or metallic debris travel through outer space, but some of this directed to Earth. It is usually small than asteroids and contain less water and ice than comets.
• Asteroid are small and rocky objects that orbit the Sun. Mostly they could found in the asteroid belt except for Trojan asteroid that nearly shares orbit with planet Jupiter. The 4 largest asteroid: Ceres, Vesta, Pallas and Hygeia.
•Comets is a cosmic snowballs of frozen gases, rock and dust that orbit the Sun. Comets, like planets, orbit the Sun in elliptical trajectories. A comet's route, on the other hand, is significantly more elliptical than any planet's. A comet is made up of four parts: the nucleus, the coma, the dust tail, and the ion tail. A comet's nucleus holds the majority of its overall mass.

Comets are icy objects that emit gasses as they orbit the sun, as I learned in today's lesson. Asteroids are rocky bodies that orbit the sun that are smaller than planets, and meteoroids are rocky or metallic fragments of asteroid planets or comets.

Since asteroids, comets, and meteoroids are the primary raw materials for planets, they are essential to the solar system. They're also significant since they're thought to be old excess from the early years of our solar system's development.

Today’s class, I erudite and gained a lot of knowledge about heavenly bodies (comets, asteroids, meteors, meteoroids and meteorites). These heavenly bodies has variances that makes them unique to others.
Comets are a cosmic snowball of dust, rock and covered by icy shell, and when comets passes through Sun it sublimates, as well as they orbit in elliptical orbit or circular shape.
In other hand, asteroids are like comets but they do not comprise of ice, asteroids are minor than planets and most of them are located in asteroid belt.
Furthermore, meteoroids are fragments of rocky debris that is smaller than asteroids, and they are commonly known as space rocks because they do not have the chance to enter Earth’s atmosphere. Moreover, meteors are also called shooting star, these are a bits of debris that burn up on the Earth atmosphere. And lastly, meteorites a rocky rubble that falls to Earth surface, it is too rare and too risky because of its small size that cannot be detected immediately.

What I Have Learned from Today's Lesson?

For today's topic I learned some information about the comets, asteroid and meteorite, meteoroids and meteors. Where Comets is like a dirty snowball, because it consists of the rocks, metal and dusts and it's also surrounded by the thick ice shell. Next is the Asteroid it is a rocky objects that is smaller than the planets. And mostly is it located in the Asteroid belt. And the last one is the meteorite, meteoroids and meteors. Meteoroid is the Rocky or metallic fragments of an Asteroid, this is called meteoroids because it haven't enter yet the earth surface. Meteorites is the meteor fragments that enters and reaches the earth surface and the Meteors is the one that we often called shooting star.

Importance of learning Comets, Asteroid and Meteoroids.

The Importance of Comets, Asteroids and Meteoroids or we often called heavenly bodies are we can learn and gained knowledge with other objects outside our earth surface not only about the planets. Because knowing this heavenly bodies can allow us to expand the knowledge that we already know about the things that happen in our universe.

What I have learned from today's lesson?
-today, I  have learned several things regarding the different celestial bodies in our solar system. Those are the following:

___________________
COMETS- are large celestial bodies made from ice, dust, and rocky material covered by an icy shell. It travels in an elliptical orbit around the sun originating from either the Kuiper belt (short period) or Oort Cloud (long period). As it travels near the sun, it undergoes sublimation by which, its "nucleus" causes its envelope: "coma" to glow. it has 2 distinct tails: the "ion tail" comprised of charged particles and the "dust tail" made from the debris of the Sun's radiation.
*Halley's comet: one of the most famous comets that visit Earth every 75-79 years

___________________
ASTEROIDS- are also called "minor planets"; made of metals and rocky materials. The largest known asteroid is Ceres which is now categorized as a dwarf planet. Although it also orbits the sun, asteroids are comparably smaller than planets. Most asteroids could be found in the Main Asteroid Belt, except for Trojan Asteroid which nearly shares an orbit with Jupiter.
(types)
*C-type [chondrite] - made of clay and silicate rocks; dark in appearance
*S-type [stony] - made of silicate rock and nickel-iron
*M-type [mettalic] - purely made of nickel-iron

___________________
METEOROID, METEORS, and METEORITE
-the key difference between these 3 is their location in our air space.
*METEOROIDS are space debris that doesn't enter our atmosphere yet.
*METEORS which are also called "shooting stars" are meteoroids that had reached our atmosphere, but then burned up in the mesosphere.
*METEORITES, on the other hand, is their variant that had already penetrated the atmosphere and reached the Earth's surface.

For today's lesson, I've learned about the difference between comet, asteroid and meteoroid. Comets are basically dusty snowballs which orbit the Sun. They are made of ices, such as water, carbon dioxide, ammonia and methane, mixed with dust. An asteroid is a rocky object that orbits the Sun. Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids. Meteoroid is a small, rocky or metallic body revolving in interplanetary space around the Sun. A meteoroid is significantly smaller than an asteroid. Aside from that is the meteor and meteorite. Meteor are also called as shooting star since it hits the atmosphere of Earth and meteorites are fragments that hit the surface of Earth.

# data[].attributes.body
For today's lesson, I've learned about the differences between Comets, Asteroids and Meteors that is part of heavenly bodies. Comets are made up of rocks, dust and has an icy shell that revolves around the Sun then sublimate (solid to gas state). Asteroids are fragments from moons, planets and comets. It has also C,S and M types where Chondrite are the most common asteroids that composed of clay and silicate rocks. Stony type asteroids are made up of silicate materials, iron and nickle while Mettalic type of asteroids are made of iron and nickle. Let's differentiate Meteoroid, Meteors and Meteorites. Meteoroids are piece of rocks that haven't enter on the Earth's atmosphere. When a Meteoroid enters the Earth's atmosphere, we call it Meteors or shooting star because it burns up and when it landed on Earth's surface, it's now called Meteorites and it was as size of a pebble.

There are types of Asteroids, the trojan and near-Earth asteroids, located in orbital path of Jupiter and near the Earth respectively.

Asteroids are considered as the building blocks of the planets that why it plays a role in our Solar System.

What I have learned for today's lesson?
- Our lesson is about heavenly bodies, and I've learned that celestial bodies or heavenly bodies refers to all the objects we observe in the sky. Stars, planets, satellites, asteroids, meteorids, and comets are among the celestial bodies. Planets are celestial bodies that do not have their own light and heat. I've learned the parts of the comets and these are Nucleus, Coma, Ion tail and Dust tail. And even the dwarf planets, Ceres, Haumea, Makemake, Eris and Pluto. And also the differences of comets, meteoroids and asteroids.

Importance of Meteoroids, asteroids and comets.
Asteroids formed at the same period as other objects in our solar system, scientists may learn a lot about the evolution of planets and the sun from these space rocks. Scientists are interested in comets because they are primitive bodies left over from the solar system's origin. They were among the first solid entities to form in the solar nebula, the collapsing interstellar cloud of dust and gas that gave birth to the Sun and the planets. Asteroids, comets, and meteoroids are vital to the solar system because they are the primary raw materials for planet formation. They're also significant because they're thought to be old relics from our solar system's early years of creation.

Balunes, Jan Noel S.
BSED 2D

What I have learned from today's lesson?
- Today, I have learned the difference between Asteroid, Meteor, Meteorite and Comet.

Asteroids are rocky objects smaller than planets that remained after our solar system formed. Much of the remaining material from the gas and dust cloud that formed our Sun went into forming the rocky terrestrial and gas giant planets that orbit our star. Asteroids are made up of smaller dust fragments that never made it into planets.

Comets, like asteroids, are made up of leftover material from the formation of our solar system and formed around the same time. Asteroids, on the other hand, formed closer to the center of our solar system, where temperatures were higher and only rock or metal could stay solid without melting. Comets formed at greater distances from the Sun, beyond the frost or snow line and past Mars and Jupiter's orbits, where temperatures were cold enough for water to freeze.

An asteroid that tries to land on Earth but is vaporized by the Earth's atmosphere is known as a meteor. The rock's temperature rises as a result of the resistance it faces from the Earth's atmosphere. Meteor showers occur when the Earth passes by a large number of meteors at the same time, and we call them "shooting stars" when we see the glowing hot air created by these burning meteors. For example, if chunks of a comet melt away as it approaches the Sun, the debris can be left behind to dazzle Earthlings with a meteor shower later.

The topic of comets, asteroids, and meteoroids was discussed in today's lecture. Comets, which are made up of dust, rock, and ice, are frozen remnants from the birth of the solar system. This material produces a tens of millions of mile-long tail. Asteroids are stony asteroids that circle the Sun. Although asteroids circle the Sun in the same way as planets, they are considerably smaller. Meteoroids are rocky or iron-based objects that circle the sun in the same way as planets, asteroids, and comets do. Meteoroids, particularly the small particles known as micrometeoroids, are abundant throughout the solar system. They are rocky inner planets that orbit the sun, as well as gas giants that make up the outer planets. What makes a meteor, a meteoroid, and a meteorite different? They're all connected to the flashes of light known as "shooting stars," which may be seen flashing across the sky from time to time. However, depending on where we are, we call the same thing by multiple names. Meteoroids are space objects ranging in size from grains of sand to small asteroids. Meteors are fireballs or "shooting stars" that enter Earth's atmosphere (or that of another planet, such as Mars) at great speeds and burn up. A meteorite is a meteoroid that survives its journey through the atmosphere and lands on the earth.

# data[].attributes.body
Today I learned about Comets Meteoroids and Asteroids. I have learned that comet is consisting of nucleus, dust tail, ion tail, and coma. It is a cosmic snowballs of frozen gases, rocks and dust roughly the size of a small town. I also learned about asteroid as a minor planet of the inner solar system, it's composition is c-type, s-type and m-type. And lastly i learned about the difference between meteoroids, meteors and meteorites.

Others:
Trojan Asteroid- it is an asteroid belong into one of two groups which orbit the sun at the same distance as Jupiter, basically it is orbiting in the orbital path of jupiter.
Halley's Comet- it is a periodical comet with an orbital period of about 75 years.
Oort Cloud- where long period comets come from (more than 200 years)
Kuiper belt- where Short period comet come from (less than 200 years)
Asteroid belt- where most asteroids located.

IMPORTANCE OF UNDERSTANDING THESE HEAVENLY BODIES

This heavenly bodies are the remainders of material for in the coldest part of our solar system. It is believed that they brought a water and a variety of organic molecules the earth and impact of these heavenly bodies are played a major role in the evolution of our earth.

Asteroids, like the four planets closest to our sun, are formed of rock and iron, although they are considerably smaller. The total mass of all asteroids would be less than our moon. Asteroids are different from comets, which are mostly rock and ice. Comets are characterized by their tails. Astronomers use asteroids and comets to chart the evolution of the solar system. The majority of the material that comprised our solar system, including Earth, did not survive. Only a small percentage of it fell into the sun or was ejected beyond the reach of our most powerful telescopes, forming the planets.
A tiny stony object that orbits the Sun is known as an asteroid. A meteor occurs when a small piece of an asteroid or comet, known as a meteoroid, enters Earth's atmosphere and burns up.
