Uranus and Neptune are the furthest planets in the solar system. Uranus is about 2.9 billion kilometers away from the Sun, while Neptune is about 4.5 billion kilometers away from the Sun. These two planets are also called ice giant planets due to their extreme cold temperature and methane-rich atmosphere which also makes them look blue in colour, this because methane absorbs other colours and reflected blue. The surface of these planets is liquid but get denser heading toward the core.
Uranus is one of the two planets in the solar system that rotate on their side, the other one is Venus. Uranus and Venus rotate clockwise (from east to west) while the rest planets in the solar system rotate counterclockwise.
Did you know that it rains diamond on Uranus and Neptune?
While here on the planet we live "planet earth" it uses to rain water or snows during winter season in some areas, things are quite different in Uranus and Neptune where it rains diamond.
The scientific research shows that temperature and pressure conditions are so extreme on these planets that carbon atoms could be crushed into diamonds in their atmospheres which results to diamond rain. But since these planets lack solid surface the diamonds sink through the ice layer and accumulate around the solid cores of the planets forming a thick diamond layer.
Diamonds are precious stones, aren't they? but unfortunately it's impossible for human to go and grab them from these planets because our technology is very poor to take us there but also the extreme weather condition that do not support us to get there.
