Solar system & How the Earth was formed?

# data[].attributes.body
The solar system, which consists of the sun at the centre and eight planets orbiting the sun, began to develop nearly five billion years ago. First, the sun was formed and then each of the planets. Some of the gas and dust travelling around the sun combined and made a thick cloud of particles that carried on orbiting the sun. The cloud was drawn closer and closer together until the particles were so tightly packed to form a solid ball. The ball began to heat up from inside until all materials had melted. Once the earth had formed into a dense molten mass, it’s surface began to cool and solidify into the rock, forming the earth’s crust. Clouds of water vapour condensed into rain, which further cooled the surface and began to form oceans. Carbon dioxide and other gases wrapped the planet in an atmosphere that provided the rest of ingredients for life.

What is there in a black hole?
Arjun Sharma

# data[].attributes.body
I know that the solar system has 8 planets and all of them are made out of rock. The only planet that does not have land is Saturn. It's rings are made out rock and ice. There is also a black hole in space. A black hole is something that sucks everything up. It is an invisible ring but scientists know that it is there. HOW? When a rocket or space shuttle went to space it never came back that is how the scientists knew it is there. A black hole is formed when a star dies. A black hole spins so fast that light cannot escape it! Even Jupiter is the biggest planet. We were shown a video too and I learnt that there is a yellow dwarf star named Sol. It is a fiery furnace at the heart of a great solar system. It has 5 dwarf planets 176 moons and billions of comets and asteroids. There is a MONSTER of swirling gas and 66 moons. One of them erupts huge jets of fire!
I wonder what is inside a black hole? Another dimension or galaxy?

Deep within the universe in the
Milky way there is a solar system which has a hot sun that is the heart of the solar system it is made up of 74 percent hydrogen, 24 percent helium and 1 percent oxygen. Then there are 8 planets called Mercury, Venus, Mars,
Earth in which we humans live, Saturn, Jupiter, Uranus, Neptune. There are close to 350 moons in the Solar System. There are total 175 moons which orbit 8 planets in the solar system and there are 9 moons which orbit 5 dwarf planets and rest of them orbit other solar system bodies
like asteroids etc. There are million or billions of asteroids and comets and meteor in fact
there is a whole an asteroid belt after the planet Mars. There are 5 dwarf planets called Pluto, Eris, Ceres, Haumea, Make Make.The suns  temperature is
56662 K. Every thing in the solar system  is orbiting the sun because of its gravity.
The solar system ends with a shield that is full of clouds called the ork cloud. Now I will share some interesting facts about the solar system.
Sun 93 million miles away from the earth. The light from the sun takes only 8 minutes to come to earth. Jupiter is the biggest planet it will take 1,321 earths and the smallest is Mercury. A planets Gravity makes a planet round.Mercury, Venus, Earth and mars are made of rocks and Jupiter,Saturn, Uranus, Neptune are made of Gas like hydrogen
and helium and ice.

1. Is there any planet except earth which has life?
2. What are planets made of?

# data[].attributes.body
I know that the solar system has no oxygen. The saturn rings are made of ice and dust. There are billions of stars in the solar system.  There are 8 planets. Mercury is one closest to the sun therefore it is the hottest planet in the solar system.  Which makes Neptune the coldest one. The sun is a yellow dwarf star which is boiling hot. If anyone comes close they will melt  .

1. Solar System has 8 planets. In order, going from the closest planet to the Sun, to the one that is farthest away, they are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
2. It includes the Sun and all other objects orbit around it due to the gravity.
3. It includes planets, asteroids,moon, comets and meteoroids.
4. Solar system formed around 4.6 billion years ago.
5.Not everything in the Solar system orbits directly around the Sun. The Moon orbits around the Earth.
6.The biggest planet is Jupiter ( it could fit 1,321 planets the size of Earth inside it), and the smallest planet is Mercury.

1) the solar system has 8 planets
2) pluto is not a planet it is a dwarf planet.
3) space has 0 gravity and that is why we flout in space.

How much is the distance between each planets and sun. Do any planet except Earth has life. How much time does each planet take to revolve around sun. What are these planets made up off and how were they made.

Why are there stars in the sky?

I know that the solar system has no oxygen level only if we are close to earth there will be around 10 % to 20 % of oxygen and air .and I know that the biggest star in the solar system is the son and few small planets are dwarf planets because they are really small .that there are billions of stars and asteroids .
