The Romans named the planet after their god of war.
It has a thin atmosphere and is mostly composed of carbon dioxide.
The planet is one-sixth the size of Earth and estimated to be over 142 million miles from the sun.
It takes 24 hours, 37 mins and 22 seconds to rotate once on its axis hence this is a Mars day.
Mars does take twice the time the Earth takes to complete a full revolution around the sun.
It has its own weather pattern having seasonal changes and has polar ice caps.
On Mars the temperature is on average minus 80 degrees Fahrenheit. In winter near the poles it can go down to minus 195 degrees Fahrenheit.

There is also nitrogen and argon and small amounts of water and methane.
Mars has the tallest mountain in the solar system called Olympus Mons. It s more than 21 km high and is about three times taller than Mount Everest and is more than 600 km in diameter.
Because of less gravity you would weigh less than twice your weight on Mars.
As the oxygen is so thin you would not be able to breath on Mars without a spacesuit and an oxygen cylinder.
The month of March is derived from the name Mars.
The first aircraft to reach Mars took 228 days to get there.
