Planets in Our Solar System

Mars Facts

Mars Planet Profile

Mass: 6.39 × 10^23 kg (0.107 M⊕)
Moons: Deimos, Phobos
Surface Area – 144.8 million km²

Mars has a nickname which is Red Planet. The planet is covered with rusted dust which gives it a red appearance. The atmosphere of the planet is pinkish red. Scientists say that Planet Mars could have signs of life as it has water. Water is essential for human existence because water is needed for the nourishment of crops and without crops, herbivores cannot survive. NASA is sending a probe to discover the planet. Here are some facts about the planet which you would be interested to know!

  • The planet is much colder than Planet Earth.
  • The planet experiences dust storms which are violent.
  • Mars planet has many volcanoes on the surface and it possesses the largest volcano in the entire solar system called the Olympus Mons. It is 21 kilometres high.
  • The planet has a thin atmosphere which is mainly made of carbon dioxide. If a planet has a thick atmosphere, it is able to trap the heat of the sun just like Venus does. So, the planet Mars is cold and the temperature is usually -120 degrees on a wintry night.
  • Water erosion might be possible on the planet as it has many canyons, plains and channels on the surface.
  • The gravity of Planet Mars is weak.
  • There are frozen ice caps on Mars which could mean that life existed on Planet Mars.
  • Mars also goes through seasons like Planet Earth.
