  4. Discovery • Egyptians -Originally named the planet -Greek god of war (Ares) • Nicolaus Copernicus -Saw Mars through a telescope • Christian Huygens -First to notice characteristics

  5. Distances • Order from Sun Sun-Mercury-Venus-Earth-Mars • Distance from Sun - 227,900,000 km • Distance from Earth - 56,000,000 km

  6. Measurements Mass: 641,693,000,000,000,000,000,000 km Volume: 163,115,609,799 km^3 Density: 3.934 g/cm^3 -Sink in water Gravity: 3.71 m/s^2 (Earth weight)- 100 pounds (Mars weight)- 38 pounds

  7. Orbit and Rotation Orbit the sun- 686.971 days Rotating on own axis- 24.623 hours

  8. Composition What is Mars made up of? -Carbon Dioxide -Nitrogen -Argon Rocky surface Red features Very dusty Thin atmosphere

  9. Temperature Very large temperature range (-125* C to 23* C)

  10. Weather Summer and Day Time- 20* C Winter and Night Time- -140* C Temperatures vary throughout the day

  11. Rings/Moons No Rings 2 moons -Phobos: Larger and More Craters -Demos: Smaller and Less Craters Discovered in 1877 by Asaph Hall

  12. Water/Living Place? There are ice patches found on the North and South poles Sustain Life? -The person would suffocate -Not high gravity force -38% lighter -Mars is cold

  13. Interesting Facts Mars crust is thicker than Earth’s and only has one plate while the Earth has several During Winter, 20% of the air freezes because of how cold Mars gets. Twice as long seasons than Earth
