Deimos (moon) - Encyclopedia, History, Geography and Biography (723 words)
Deimos (IPA /ˈdaɪməs/ or /ˈdiːməs/; Greek Δείμος: "Dread"), is the smaller and outermost of Mars’ two moons, named after Deimos from Greek Mythology.
Deimos was discovered on August 12, 1877 at about 07:48 UTC (given in contemporary sources as "August 11 14:40" Washington mean time using the old astronomical convention of beginning a day at noon, so 12 hours must be added to get the actual local mean time) [1].
Deimos is composed of rock rich in carbonaceous material, much like C-type asteroids and carbonaceous chondrite meteorites.
Reference.com/Encyclopedia/Phobos (moon) (1441 words)
Phobos was discovered by American astronomer Asaph Hall on August 18, 1877, at the US Naval Observatory in Washington, D.C., at about 09:14 GMT (contemporary sources, using the pre-1925 astronomical convention that began the day at noon, give the time of discovery as August 17 16:06 Washington mean time).
Phobos' low orbit means that Phobos will eventually be destroyed: tidal forces are lowering its orbit, currently at the rate of about 1.8 metres per century, and in 30-80 million years it will either impact the surface of Mars or (more likely) break up into a planetary ring.
Phobos' density is too low to be pure rock, however, and it is known to have significant porosity.
