Mars’ Atmosphere • Thin atmosphere • Consists of Carbon Dioxide, Nitrogen, and Argon Distances • 4th planet from the Sun Distance from sun- 227,900,000 km Distance from the earth- 56,000,000 km Temperatures • Mars has a very large temperature range • (-125* C to 23* C) Orbit/Rotation • It takes 686.971 days for Mars to orbit the Sun • It takes 24.623 hours for Mars to rotate on its own axis Composition • One of the terrestrial planets (rocky) • The crust of the planet is cold, and it gets warmer closer to the core Water & Rings • Mars is too cold to have liquid water, but on the Northern and Southern poles, there are meters of thick ice caps • Mars has no rings Weather • Changes dramatically • Dry/cold/clear • Can change 110* C in one night • Has seasons • Can get to -140*C in the winter Moons • 2 moons • Phobos and Deimos • Both were discovered in 1877 by Asaph Hall • Phobos- larger moon • Deimos- smaller moon Human Travel to Mars…? • Less gravity on Mars than Earth… you would float around • You would freeze because of the cold temperatures Bibliography "Mars Symbol Clip Art Free Vector."
