Phobos (mythology)

In Greek mythology, Phobos was the son of Mars. He had a brother named Deimos. The moons of the planet Mars were therefore named Phobos and Deimos. Phobos was also the Greek word for fear. (AUDIO: Phobos)

Behind the scenes
Phobos and Deimos are actually the sons of Ares, the Greek equivalent of Mars.
