Acceleration Due To Gravity

The prediction for the acceleration due to gravity on mars is (3.8m/s/s). Earth's acceleration due to gravity is (9.8m/s/s). So there is a quite a big difference between Mars' and Earth's acceleration due to gravity.

Mars' Moons

Mars has two moons the one on the..

Left is called Phobis and it dominated by Stickney crater. Is was named after a messanger of the Roman god of war, it is the larger of Mars' two moons and 27 by 22 by 18 km in diameter.

Right is called Demimos and is named after the Roman god of dread, Demimos is the smaller of Mars' two moons. Only 15 by 12 by 11 km in size, Deimos whirls around Mars every 30 hours
