Mars

Mars is known as the red planet, and is the fourth from the sun. It may have once had water on it's surface. Its climate is a lot in common with Earth.

Appearance
Mars appears reddish and it has the smallest moons of the solar system. It is also far enough from the sun to have ice on its surface. Mars appears red because it has a large amount of iron in it's surface.

Moons
Mars has 2 moons, Deimos is the smaller one, and Phobos being the larger one. In the future, scientists predict that Phobos will be crushed by Mars's gravity and Mars will get its own ring.

Facts
Mars may be the planet to move to when the sun explodes (which will happen in 4.5 billion years). It has a thin layer of its atmosphere, which means that it can't possibly be habitable. Mars is also the second smallest planet, with weak gravity. A bunch of rovers have landed on Mars, which include Vikings 1 and 2, Curiosity, Opportunity, and Perseverance. A year on Mars is 687 years and a day on Mars is around 24 hours.
