Jupiter

jacktarr03 — 2018-10-07 17:29:27 UTC

What is the size of Jupiter?
Jupiter has a radius of 69,911km which makes it the largest planet in the solar system.
What is the planet made of?
Jupiter is predominantly composed of hydrogen and helium, giving it the title "gas planet".
How far is the planet from Earth?
At their closest point during their orbits, Jupiter and Earth are just 588 million kilometers away! At their furthest, they are 968 million kilometers apart.
How far is the planet from the sun? 
At it's closest - during orbit -  Jupiter sits 741 million kilometers away from the sun and it's furthest distance from the sun is 817 million kilometers.
How long is one rotation on Jupiter?
Jupiter has a single rotation time of 9 hours and 50 minutes at the equator. Polar regions (far northern and southern ends of the planet) will finish the rotation with a 6 minute delay as the planet is purely gasses and follows the equator with a trail
How long is one orbit on Jupiter?
Jupiter's orbit takes 12 Earth years
DID YOU KNOW?
- If you parachute into Jupiter you will not find a firm place to land as it is purely just gas.
- Jupiter is 318 times bigger than Earth, in fact it is 2.5 times bigger than all of the other planets in the solar system combined!
- Jupiter has 67 moons!
- You can see Jupiter with your own eyes! How? It is the third brightest object in our solar system, it can be seen as a unusually big bright star, if you have a telescope you may be able to see its moons next to as well!

Uranus

What is the size of Uranus?
Uranus is the third largest planet in our solar system. It has an average diameter of 50,724 kilometres and a circumference of 159,354 km.
What is Uranus made of?
Uranus is known as an ice giant for being a gaseous planet comprised mostly of water and other ices. Its upper atmosphere is made of water, ammonia and methane ice crystals. These methane ice crystals are what give Uranus its pale, blue colour.
How far is Uranus from Earth?
The closest Uranus gets to Earth is about 2.6 billion kilometres and 3.2 billion kilometres at their furthest.
How far is Uranus from the Sun?
At its closest, Uranus is 2.5 billion kilometres from the Sun. At the furthest part of its orbit, Uranus can be found 3 billion kilometres away.
How long is one rotation on Uranus?
A full rotation of Uranus takes 17.24 hours.
How long is one orbit of Uranus?
It takes Uranus 84 years to complete a full orbit of the Sun.
Interesting facts
Uranus rotates in the opposite direction to Earth
Uranus was officially discovered in 1781, before that, it had not been recognised as a planet even though it can be seen with the naked eye
Uranus' temperature can get as low as -224°C
Due to an axial tilt of 98 degrees, Uranus looks as though it is rolling around the sun.

Neptune

What is the size of Neptune?
Neptune is the fourth largest planet in the solar system. It has an average diameter of 49,244 km. It has a circumference of 154,705 km.
What is Neptune made of?
Neptune is known as an ice giant for being a gaseous planet comprised mostly of water and other ices. Its surface is mostly water and melted ice slush.

It takes sixteen hours and six minutes to complete one full rotation on Neptune.
How long is one orbit of Neptune?
Neptune takes 164.79 years to orbit the sun. July 11th, 2011 was the first time it had completed an orbit since its discovery.
Interesting facts
It's theorised that Neptune was formed closer to the Sun and then migrated out to its location as the most distant planet we know it as today
Neptune has a storm known as The Great Dark Spot, the storm was roughly the size of Earth and lasted about five years

VENUS

chelsea_e_obrien97 — 2018-10-08 09:19:57 UTC

What is the size of Venus?
Venus has a mean radius 6,052 kilometres.

A trip around the equator of Venus would carry you 38,025 kilometres.

What is Venus made of?
Rocky ground lies underneath the layers of clouds, but unlike Mars and Mercury, Venus has a relatively smooth surface.

Scientists think that it’s interior is much like Earth’s own. The mantle is probably rocky and the core is probably somewhat liquid.

The core may also be completely solid, or may not even exist at all. Taking readings on the interior of another planet is a significant challenge. It’s atmosphere is mainly made up of carbon dioxide.

How far is Venus from Earth?
At its farthest, Venus lies 261 million kilometres away from Earth, according to NASA. It can reach as close as 38 million kilometres.

Because of their orbits, the distance between them is constantly shifting.
How far is Venus from the
Sun?
Venus has the most circular orbit of the planets. On average, the distance of Venus from the Sun is 108 million kilometres.
How long is one rotation on Venus?
A day on Venus lasts 243 Earth days.
How long is one orbit of Venus?
It's orbital period is 224.65 days.
Interesting facts:
- Venus rotates clockwise
- The sun rises in the West and sets in the East

MARS

What is the size of Mars?
Mars has a radius of 3,390 kilometres.
What is Mars made of?
The soil of mars is made up of nutrients such as sodium, potassium, chloride and magnesium.
How far is Mars from Earth?
Mars is 54.6 million kilometres away from Earth
How far is Mars from the sun?
Mars is 227.9 million kilometres from the sun
How long is one rotation of Mars?
Mars spins 868.22 kilometres per hour.
How long is one orbit on Mars?
It takes 687 days for Mars to orbit around the sun.
Interesting Facts:
Mars is the fourth planet from the sun.
