Viewed from the Sun, Mars is the fourth planet in our solar system. This celestial object is located between the orbits of the Earth and Jupiter and is often called the “red” or “orange” planet since this planet can be seen from the Earth as a bright reddish star. Like the planets Mercury, Venus and the Earth, Mars is also a terrestrial planet with a thin atmosphere.
Mars undoubtedly has the most similarities with the Earth in all respects, but thanks to its very thin atmosphere and a lack of magnetic field and magnetosphere, life on Mars is impossible today. Mars gets its name from the Roman god of war. This planet already stood out in Antiquity because its orbit between the stars was irregular and because the brightness of Mars sometimes increased spectacularly.
