Interesting Facts
There is an Asteroid Belt between Mars and Jupiter
There is a picture of a face and couple of pyramids in the Cydonia Region on Mars
Mars is also known as the Red Planet because of its reddish colored surface.
The surface is reddish in color because of rust-colored substance, called iron oxides
Observation on Mars were first made by Galileo in 1610
Mars is half the size of Earth
Mar's axis tilts at an angle of about 24 degrees
Mars has a thin atmosphere
The atmosphere of Mars is 1/100 less thicker than Earth.
Mars is about 4/5 as dense as the Earth
One of the largest volcanoes on Mars is called Olympus Mons which is 15.5 miles (25 km) high and more than 340 miles (550 km) across at its base.
Olympus Mons is three times as higher than Mt. Everest and 100 times larger than Mauna Loa, in Hawaii, but right now it's a dormant volcano.
There is an enormous canyon called the Valles Marineris, that extends 3000 miles(5000 km) a long the equatorial belt, 300 miles wide and drops to more than 4 miles below the surrounding surface.
If this canyon was on earth, it would stretch from New York to California
There are polar caps on Mars. The North Polar Cap contains frozen water, which never melts, and the southern polar cap contains frozen carbon dioxide (dry ice).
