Deimos and Phobos are the only two known natural satellites of the planet Mars. They are named after the ancient Greek gods (Phobos is the god of panic fear, flight and battlefield rout; and Demos is the god of fear, dread and terror).
Phobos is the larger (26.8 × 22.4 × 18.4 km) of the two moons and orbits closer (9,377.2 km) to Mars. It is speculated that Phobos may have vast caverns within the moon.
Deimos is (15 × 12.2 × 10.4 km) and orbits at a mean distance of (23,460 km) from Mars.
Both bodies are thought to be captured asteroids or comets and are too small to be round.
Deimos was discovered by astronomer Asaph Hall on August 12, 1877.
Phobos was discovered by astronomer Asaph Hall on August 18, 1877.
Faint dust rings produced by Phobos and Deimos have long been predicted but attempts to observe these rings have, to date, failed. Thus as far as we know to date Mars has no rings.
