Mars

Mars is the 4th planet in the Solar System. It is about half the size of Earth. Mars has always fascinated people, being the closest planet to Earth. Humans have always searched for proof of life on the "Red Planet".

Mars (right) compared to Earth
Recently, NASA's vehicle Curiosity on Mars, has discovered core elements that are necessary for life. This shows that there could have been life on Mars a long time ago.

One of the most interesting things about Mars is Olympus Mons (Mount Olympus). This is the highest planetary volcano/mountain in the Solar System, with a height of almost 26 kilometers.

Olympus Mons compared to Mt. Everest
A year on Mars lasts 1,8809 Earth years, or roughly 1 year and 320 days.

Mars has 2 moons, Phobos and Deimos. It is expected that -due to gravitational pull- Phobos will collide with Mars or disintegrate into a ring around Mars in about 50 million years.
