Which moon of the solar system is named after the Greek god of fear?
"Mean Time, using an astronomical convention of beginning a day at noon, so 12 hours must be added to get the actual local mean time). Hall also discovered Phobos on 18 August 1877, at about 09:14 GMT, after deliberately searching for Martian moons. It is named after Deimos, a figure representing dread in Greek mythology. The names, at first spelled ""Phobus"" and ""Deimus"", were suggested by Henry Madan (1838–1901), Science Master of Eton, from Book XV of the ""Iliad"", where Ares (the Roman god Mars) summons Dread (Deimos) and Fear (Phobos). Deimos, like Mars's other moon, Phobos, has spectra, albedos,"
"Phobos (moon) Phobos ( , , ; systematic designation: ) is the innermost and larger of the two natural satellites of Mars, the other being Deimos. Both moons were discovered in 1877 by American astronomer Asaph Hall. Phobos is a small, irregularly shaped object with a mean radius of and is seven times as massive as the outer moon, Deimos. Phobos is named after the Greek god Phobos, a son of Ares (Mars) and Aphrodite (Venus) and the personification of horror (cf. phobia). Phobos orbits from the Martian surface, closer to its primary body than any other known planetary moon."
"Moons of Mars The two moons of Mars are Phobos and Deimos. Both were discovered by Asaph Hall in August 1877 and are named after the Greek mythological twin characters Phobos (panic/fear) and Deimos (terror/dread) who accompanied their father Ares, god of war, into battle. Ares was known as Mars to the Romans. Phobos orbits closer to Mars, with a semi-major axis of to Deimos' .

Mars was the Roman counterpart of Ares. In modern Greek, the planet retains its ancient name ""Ares"" (Aris: ""Άρης""). From the surface of Mars, the motions of Phobos and Deimos appear different from that of the Moon. Phobos rises in the west, sets in the east, and rises again in just 11 hours.

He is the twin brother of Phobos and nephew of the goddess Enyo who accompanied her brother Ares into battle, as well as his father's attendants, Trembling, Fear, Dread and Panic. Deimos is more of a personification and an abstraction of the sheer terror that is brought by war and he never appeared as an actual character in any story in Greek Mythology.

American astronomer Asaph Hall named a satellite of the planet Mars, ""Phobos"", which he discovered along with the second Mars satellite, ""Deimos"", in 1877. Phobos is the larger of the two satellites. The word ""phobia"" derives from ""phobos"", (Φόβος), meaning fear. The two brothers Deimos and Phobos were particularly worshipped in the city state of ""Sparta"" as they were the sons of Ares, the god of war. Phobos in Greek literally means ""fear"" ().

"for newly discovered Neptunian moons is to accord with these first two choices by naming them after Greek sea deities. Neptune XIV, the most recently discovered Neptunian moon, was given a Roman numeral but not a name. The name of Pluto's moon Charon was suggested by James W. Christy, its discoverer, soon after its discovery. The other four moons are named Hydra, Nix, Kerberos, and Styx. Charon, Hydra, Nix, and Kerberos are all characters in Greek mythology, with ties to Hades (the Greek equivalent of Pluto).

The etymology of ""Selene"" is uncertain, but if the name is of Greek origin, it is likely connected to the word ""selas"" (σέλας), meaning ""light"". Just as Helios, from his identification with Apollo, is called ""Phoebus"" (""bright""), Selene, from her identification with Artemis, is also commonly referred to by the epithet ""Phoebe"" (feminine form).

For instance, the second month, Metageitnion, is named after a cult title of the god Apollo, but there is no trace of a festival bearing the name. The same goes for months 5 and 6, Maimakterion and Poseideon. The calendars of the Ionian cities of Asia Minor (along the western coastline of modern Turkey) often share month names with Athens.

A shadowy figure, Nyx stood at or near the beginning of creation and mothered other personified deities such as Hypnos (Sleep) and Thanatos (Death), with Erebus (Darkness). Her appearances are sparse in surviving mythology, but reveal her as a figure of such exceptional power and beauty that she is feared by Zeus himself. In Hesiod's ""Theogony"", Nyx is born of Chaos. With Erebus (Darkness), Nyx gives birth to Aether (Brightness) and Hemera (Day). Later, on her own, Nyx gives birth to Moros (Doom, Destiny),"
"mass. It is named after the Greek mythological nymph Callisto, a lover of Zeus who was a daughter of the Arkadian King Lykaon and a hunting companion of the goddess Artemis. The moon does not form part of the orbital resonance that affects three inner Galilean satellites and thus does not experience appreciable tidal heating. Callisto is composed of approximately equal amounts of rock and ices, which makes it the least dense of the Galilean moons. It is one of the most heavily cratered satellites in the Solar System, and one major feature is a basin around 3000 km wide"

Proteus orbits Neptune in a nearly equatorial orbit at the distance of about 4.75 equatorial radii of the planet.
