Document Summary
Contains 2 moons that are odd shaped = captured asteroids. Themos orbit the same way mars rotates in 8 hours. Phobos takes 30 hours because it is further away and still reacts with mars atmosphere. Moon tell us how the solar system formed and not how mars was formed. Orbiting at 5. 2 au from the sun corresponds with keplers laws for 11. 8 years. Does not rotate in one mass therefore eqitorial regions move at a different rate than polar regions. Rotates so quickly it is oblique ( thicker at equator than poles) very large atmosphere of hydrogen and helium. Large storm known as the great red spot(hurricane) continuous for over. Rapid rotation rate of the storm wraps around the entire planet because it doesn"t have time to form wrap around 1 centre. Colours is due to warm materials rises and sinking.
