Mars Facts

  1. TheDoctor
    Mars is red because it is rusty. There is a lot of iron in the soil, and the air on Mars has made it turn red-just like rusty iron on Earth.

    One of Mars' moons, Phobos, is moving closer and closer to Mars. Scientists think that one day it will crash into Mars.

    Mars has the tallest Volcano in the Solar System named Olympus Mons and it is 15 miles high which is three times the height of Mount Everest.

    Like Earth, the poles of Mars are covered in ice. The ice becomes thicker in the winter.

    Mars orbits the sun every 687 Earth days.

    The Martian “day” is about half a hour longer than Earth.

    The thin atmosphere of Mars is made of mostly carbon dioxide.

    A hundred pound man would weight 38 pounds on Mars. (I like this one)

    In winter, nighttime temperatures on Mars can drop as low as -191°F.

    Wow. Some nice facts. Long live the Red Planet, God of War!

    Cheers, and clear skies,

    There's some more:

    *Mars has 2 moons - Phobos and Deimos and their names mean 'fear' and 'horror' in latin.
    *Mars is the most studied planet in the solar system.
    *There are huge dust storms on Mars which can last for a year and cover the whole planet.
    *The astronomers are thinking about building dome cities on Mars in the future.
    *Scientists have thought about terraforming of Mars - it would take approximately 900 years, but eventually Mars would be inhabitable for humans - it would have air for breathing and it would be warm enough.
    *Olympus Mons's diameter is about 550 km (about 340 miles).

    Hope you got some new information

    There's some more:
    1.Mars is too small as compare to Earth
    we all think that mars is twin of earth but in reality diameter of mars is only 6,800 km across which is half the diameter of Earth.With the smaller size comes an even smaller mass. The total mass of Mars is only about 10% the mass of Earth. The surface gravity is only 37% what you would experience on Earth. In other words, you would be able to jump 3 times as high on Mars as you can on Earth.

    2.Mars has the tallest mountain in the Solar System
    The tallest mountain in the Solar System is the mighty Olympus Mons on Mars. It rises up 27 kilometers above the surrounding plains. Olympus Mons is a shield volcano, like Hawaii’s Mauna Kea, and formed gradually over billions of years. Some lava flows on the volcano are so young that planetary scientists think that it might still be active.

    3.And Mars has the longest, deepest canyon in the Solar System
    One of the most distinct features on the surface of Mars is the Valles Marineris canyon. It stretches 4,000 km along the equator of Mars, and can be as deep as 7 km in places. If you could move the Valles Marineris to Earth, it would stretch right across the United States.

    4.Mars has almost no atmosphere
    If you tried to stand out on the surface of Mars without a spacesuit, you would die almost immediately. The freezing cold temperatures would be a problem, but even worse is the thin atmosphere. The air pressure at the surface of Mars is only 1% the pressure we enjoy here on Earth. And the atmosphere on Mars consists of 95% carbon dioxide, 3% nitrogen, 1.6% argon and trace amounts of water and oxygen.
