Phobos, Mars' closest satellite, come from the Greek word meaning 'fear', whilst Deimos means 'panic', both following on from the Mars/War theme. Orbiting at a meagre 6000km from the surface of Mars, Phobos is the closest moon to its' parent planet in the Solar System (at least that we know of), whilst Deimos is the smallest known solar system satellite.
Phobos and Deimos are both believed to be captured asteroids, due to their irregular shape and small size (Phobos having a 22.2km wide diameter, whilst Deimos is just 12.6km wide!). Both moons are, however, heavily cratered and are believed to be made up of rock and ice. Like our moon they have a coating of dust on their surfaces. Phobos' orbit is such that it rises in the west and sets in the east, often more than once in one day.
However, I'm afraid there isn't realy much future left for Phobos as an independent moon of Mars. This is because in little over 50 million years it is destined to crash into Mars (with a thud) due to the planet's tidal forces lowering its orbit (presently at about 1.8cm/year). Nevertheless, it (and Deimos) have been seen by many spacecraft since it was discovered by Asaph Hall in 1877, such as the Mariner 9, Viking 1, Phobos and Phobos 2, the last of which even detected an outgassing coming from Phobos.
Yes, Phobos is bigger than Deimos. Phobos mass is .00000018 and Deimos mass is .000000024. Phobos is 12X8 (miles) and Deimos is 7X6
Phobos, It is also the moon that orbits closer to Mars... yes i know Deimos is a loner.
Mars has two moons: Phobos and Deimos. Both moons are irregularly shaped and are thought to be captured asteroids from the asteroid belt.
Phobos is the larger of Mars' two moons. It has a diameter of about 22.4 kilometers, while Deimos is smaller with a diameter of about 12.4 kilometers.
it has two moons... they are called phobos and deimos
The answer for this question is Phobos. Phobos is bigger than Deimos. Phobos and Deimos are the moons on Mars.
Yes, Phobos is bigger than Deimos. Phobos mass is .00000018 and Deimos mass is .000000024. Phobos is 12X8 (miles) and Deimos is 7X6
YES

Phobos and Deimos are the moons of Mars.
phobos and deimos
The moons Phobos and Deimos revolve around the planet Mars.
Deimos eclipse in March 4 2004. Phobos eclipse in March 7 2004.
The two moons of Mars are named Phobos and Deimos. Phobos is the larger and closer of the two, while Deimos is smaller and farther from Mars.
Asaph Hall in 1877 discovered them and call them Phobos & Deimos.
