Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] Joan Cartan-Hansen, Host: Mars has not one but two moons: Phobos and Deimos.
Phobos is about 14 miles across.
It orbits only 37 hundred miles above the surface of Mars and zips around the planet three times a day.
Deimos is smaller at only about eight miles across.
It orbits more than 12 thousand miles above the surface.
And takes about 30 hours to travel around Mars.
Both look more like asteroids.
They're shaped kind of like lumpy potatoes and have lots of craters on their surface.
And unlike our Moon, the moons around Mars are not in a stable orbit.
Phobos is slowly spiraling inward to the surface.
So within 50 million years, it will either collide with Mars or break apart into a ring of rubble.
Deimos, on the other hand, is slowly drifting away from Mars.
It will eventually just float off into space.
