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

| 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. |

earth, it would stretch from New York to
California |

Mars. The North Polar Cap contains frozen water,
which never melts, and the southern polar cap
contains frozen carbon dioxide (dry ice). |
