We are busy gathering more information on the different planets that orbits our Sun.
Lets have a look at Mars and Jupiter. The 4th and 5th planet from the Sun. Earth is the 3rd planet from the Sun - the only planet which has ideal conditions for us to live - not too hot, not too cold and enough oxygen. Another reason why it is so important to look after our planet - we cannot just move to another one. We will later look at Earth more in detail, for now we will gather extra information on the other planets.
Mars, or the 'Red Planet' as it is sometimes known, has a dusty, rocky surface and a thin atmosphere. Its relatively calm conditions and close proximity to earth make it the most likely destination for future planet exploration by humans.
A few successful and unsuccessful missions has been launched to Mars to make discoveries and see if it will be a likely place for humans to live in future.
The planet go its name the red planet from the fact that it is covered with red dust and even the clouds around the planet is pinkish in color because of all the red dust that moves around.
There are many volcanoes on this planet and the biggest one in our Solar system (Olympus Mons) is found on Mars. The volcano is 21 km high and the base is 600 km.
The atmosphere of Mars, which is mainly made up of carbon dioxide, is very thin, so it does not trap any heat and it becomes very cold in winter and the temperature can drop to minus 120 degrees Celsius and can go up to 25 degrees Celsius.
The gravity of Mars is very weak and it cannot hold onto the atmosphere which drifts away.
Jupiter is a huge planet. So big that you can fit more than a 1300 Earths in it - it also has many moons and raging gas storms.
There are beautiful and colorful clouds that surround this planet, but do not be fooled by its appearance - these clouds are poisonous. The planet also spins so fast that it 'whips up' the atmosphere and looks like bands surrounding Jupiter.
If it was possible for you to go through these clouds to the surface, you will be squished before you reach the surface - the closer you get to the surface, the darker, hotter and thicker the clouds become and the pressure increases so much that the atmosphere turns to liquid.
Jupiter has a red spot that can be seen through a telescope. This is actually a tornado that is raging on the planet and it has been there for more than 300 years.
The magnetic field on Jupiter is very strong so you would be pulled toward the planet with a lot of force and you will weigh two and a half times more than on Earth.
Jupiter has many moons circling around it. Four of these moons are bigger than Pluto.
