Size and position:
Mars is the fourth planet from the Sun, just after the Earth. It is smaller than the Earth, with a diameter of about 6780 kilometers, a little more than half of the Earth.

Satellites:
Mars has two natural satellites, Phobos and Deimos, which are relatively small and irregular.

Atmosphere :
The atmosphere of Mars is composed mainly of carbon dioxide (95%), with small amounts of nitrogen, argon and traces of oxygen and water.
The atmospheric pressure at the surface is about 1% of that on Earth.

Relief :
Mars has a rugged surface, with many craters, mountains, valleys and plains.
The largest volcano in the solar system, Mount Olympus, is located on Mars.

Temperature :
The average temperature of Mars is about -60%c, with large variations, which makes it much colder than Earth.

Life potential :
Mars has been identified as a potentially habitable planet and is currently being studied by space missions to determine if it has ever harbored life or if it could do so in the future.
