Mars is cool because...

  • it is cool! The average Martian temperature is -63°C, with a high record of 20°C and a low record of -140°C.
  • the Martian day is 24 hours and 37 minutes Earth time -- pretty close to ours!
  • the Martian year, on the other hand, is 687 Earth days -- nearly twice Earth's.
  • Mars's moon Phobos orbits Mars every seven hours (the Moon orbits Earth every 27.3 days.
  • Martian air contains 1/1000 as much water as Earth's, but still can form clouds, fog, and frost.
  • if you weighed 100 pounds on Earth, you would only weigh 38 on Mars.
  • the mass of Mars is 6.4219x10^23 kg, or the mass of 4,700,000,000,000,000,000 blue whales!
  • Mars has interesting magnetic fields!
  • the presence of what seem to be canals and the placement of rocks in flood-like patterns cause scientists to believe that water once existed on Mars; now the question is where it went! Some studies have said that Mars's lack of magnetosphere may have allowed the solar wind to carry off a huge amount of water from the Martian surface over billions of years.
  • it's such a challenge -- scientists conclude that living on Mars (without some kind of high-tech provisions) isn't possible because of UV rays and dry, oxidizing soil.
