[00:00:00]Mars has two moons, Phobos and Demos. Discovered in 1877, these small, irregularly shaped bodies are completely different from Earth's large round moon.

[00:00:13]Phobos, the larger of the two, orbits incredibly close to Mars.

[00:00:18]It travels around the planet three times a day and is slowly drawing closer, meaning it will eventually crash into Mars or break apart into a ring.

[00:00:28]Demos is smaller and orbits much farther away, taking about 30 hours to complete one loop.

[00:00:35]Both resemble carbon -rich asteroids, leading scientists to debate whether Mars captured them using gravity or if they formed from an ancient planetary impact.
