Facts

1.       Mars and earth have  approximately the same landmass : even though mars has only 15% of the earth’s volume & just over 10% of the earth mass, around two third of the earth’s surface is covered in water martin surface gravity is only 37% of earths ( meaning you can leap three times higher on mars).

2.       Mars is the home to the tallest mountain in the solar system. : Olympus Mons, a shield volcano, is 21 km high and 600 km in diameter. Despite having formed over billions of years, evidence from volcanic lava flows is so resent many scientists believe it could still be active.

3.       Mars has polar caps like Earth, although  mars polar caps contain mostly frozen carbon dioxide instead of frozen water

4.       Mars is believed to have had water flowing around it like Earth once. It may have had a blue sky too. However, it is unlikely that it had grass trees and plants like earth has now.

5.       Mars has seasons like Earth. This is caused by the tilt of the planet’s axis, at a similar angle to the tilt of earth’s axis.

6.       The Sun appears about half the size on mars as it does from Earth.
