The Names of the Moons and Their Meanings

No moons.
Venus Roman name for Aphrodite, goddess of love and sex. I don't know why our sister planet got this name. Maybe because its exceedingly dense clouds shroud it in mystery, and the ancients felt that that appropriately describes women and love.

No moons.
Earth Known in Greek myth as Gaea (thus fun words like "geography"), Terra to the Romans ("terracing"). The word "earth" comes from Middle English, Old English, and eventually Indo-European, making it a very old word, but with no fun story behind it. It just means dirt.

One Moon with many Greek and Roman appelations, few of which are still used today. Some common ones are Luna, Cynthia, Selene, Diana, Hecate... "Moon" again comes from Old English and Indo-European.
Mars Roman name for Ares, god of war. In Greek myth he was a coward and whiner, but was idealized and idolized by the bellicose Romans. The planet acquired the name because of its obviously red hue (blood planet and all that).

Two moons: Deimos (Greek for "fear") and Phobos ("fright"). Named after Ares's sons, who were said to often accompany him in battle. No mother takes responsibility for these dreadful children.
Jupiter Roman name for Zeus, king of the gods. He was quite a player. Most of its many, many moons were names after his lovers.

Io Zeus turned her into a white heifer to hide from Hera, his jealous wife, but was discovered and relentlessly tormented with a gadfly--an ancestor of Heracles.
Europa Seduced by Zeus in the form of a handsome bull, who then carried her off over the sea to Crete. The story is that she eventually populated the country and is where we get "Europe."
Ganymede Handsome young mortal man whom Zeus abducted to serve as his cupbearer, superceding Hebe, his daughter by Hera.
Callisto Another unfortunate lover of Zeus who was transformed by Hera into a bear along with her son. To make up for it, Zeus placed them in the sky to become Ursa Major (Big Dipper) and Ursa Minor (Little Dipper).
Amalthea The goat that fed Zeus as a babe on Crete
Himalia A Cyprian nymph who bore Zeus three sons, including Cronius
Elara Another lover; to hide her from Hera, he placed her under the earth, where she gave birth to the giant Tityas.
Pasiphae Wife of King Minos who was punished for her husband's insult to Poseidon by being forced to fall in love with a bull. With the help of Daedelus, the famous inventor, she contrived a cow costume so she could have relations with the bull. She eventually gave birth to the Minotaur; heaven knows that this has to do with Zeus.
Sinope Abducted by Apollo and became mother of Syrus, for whom the city was named; again no relation to Zeus, but still a mortal lover of a god.
Lysithea Daughter of Oceanus and lover of Zeus.
Carme An obscure lover of Zeus; they produced  Britomartis, a Cretan goddess.
Ananke As the goddess of unalterable necessity, she was the mother of the Fates, and with Zeus as the father, also produced Adrasteia, distributor of rewards and punishment.
Leda On the same day, she had sex with her husband and was raped by Zeus in the form of a swan. Eventually she gave birth to Castor, Polydeucus, Clytemnestra, and Helen (as in "of Troy"). One can only assume that since Polydeucus shares his father's immortality, that one of the sisters must as well. And since Clytemnestra's death was well documented at the hands of her son Orestes, that leaves Helen. This is never mentioned in any myth that I know of, but I find it very entertaining.
Metis Her name means "cleverness." Zeus was told that a son from Metis would destroy him, so he swallowed her up to prevent such a possiblity. Not long after, he developed a raging headache and asked Hephesteus to crack open his skull, thus releasing Athena, the goddess of wisdom.
Adrastea Mentioned above as Zeus's and Ananke's daughter, the goddess of unalterable necessity. Known to the Romans as "Nemesis."
Thebe Zeus's daughter by a Boeotian nymph named Iodame; in other stories, a lover of Zeus.
Callirrhoe None of the three Callirrhoe's in Greek myth had anything to do with Zeus. 1. An Oceanid (daughter of Oceanus--there were lots). 2. Wife of  Alcmaeon, who acquired a magic robe and necklace as her request, under the pretense of dedicating them at Delphi. When the original owners learned of the ruse, they killed Alcmaeon. Callirrhoe begged the gods to make her two sons into men immediately to avenge their father, which was granted. They killed their father's murderer and dedicated the robe and necklace to Delphi after all. 3. Woman  wooed by Coresus, the priest of Bacchus. When she denied him, Bacchus sent madness among her people, which an oracle said could only be lifted if Callirrhoe were sacrifed. Her ex-suitor Coresus was about to do the deed, but turned the knife against himself instead. She was so touched by his act that she killed herself in return, thus making his sacrifice perfectly meaningless. Dolt.
Themisto Not a very pleasant lady; she tried to kill her husband's first wife's children by dressing her own children in white and the victims in black so they could be distinguished in the dark, but the first wife switched the clothes and Themisto ended up killing her own children by mistake.
Kalyke
Iocaste Also known as Jocasta, the mother and eventual wife of Oedipus, who killed herself upon learning her second husband's identity.
Erinome Possibly related to the Erinyes (the Furies), who exacted retribution for particularly evil deeds like patricide.
Harpalyke I don't know of a figure in mythology with this name, but the Greek word means something like "greedy, devouring, alluring, attractive." It could refer to the Harpies, nasty bird-women who punished people, took their souls to the underworld, and were personifications of storms. They also stole and befouled King Phineus's food so that he nearly starved to death, until they were driven away by the Boreads.
Isonoe
Praxidike "She who exacts penalties," a goddess represented with a bare head, to whom the heads of victims were offered.
Megaclite Greek for "much inflicted"??? I don't know.
Taygete Another unfortunate woman whom Zeus took an interest in; she prayed to Artemis to rescue her and was turned her into a doe.  Zeus took advantage of her anyway and she gave birth to Lacedaemon.
Chaldene
Autonoe Mother of Acteone, who was turned into a stag and torn apart by his own hounds as punishment for accidentally seeing Artemis nakes. That goddess could be a real bitch sometimes.
Thyone (Originally names Semele, was the lover of Zeus and mother of Dionysus. Hera tricked her into asking Zeus to show himself in his full glory to her, thus burning her up into a small pile of ash. When Dionysus became a god, he retrieved her from the underworld and made her a goddess, renaming her Thyone)
Hermippe
Euporie
Aitne
Saturn Roman name for Cronos, father of Zeus and most of the pantheon. Knowing that one of his children would eventually kill him, he swallowed them each at birth. Zeus was spirited away by his mother, who gave her husband a stone in his place. When Zues was grown, he killed his father and freed his siblings from Daddy's gut. For some reason, many of Saturn's moons are named for non-Classical myth characters. Apparnetly, Chronos didn't have nearly as many naughty stories from which names could be drawn as his son Zeus.

Titan Children of Gaea and Uranus, Titans were the masters of the earth before the pantheon gods were born. Chronos was a Titan, and his son Zeus defeated him and his siblings with the help of his own siblings, thus becoming the king of the gods.

Prometheus Son of Iapetus, his name means "forethought." He endlessly took the side of mortal humans against the gods, giving them the divine fire, showing them how to trick the gods into accepting an inferior sacrifice, etc. In punishment, Zeus chained him to a rock, where his liver was eaten out by an eagle every day until Heracles killed the bird and freed him.
Pandora Means "all-gifted." To keep mortal humans from getting too uppity, Zeus devised a woman, perfect in all ways except for insatiable curiosity, and gave her a box with instruction never to open it. Of course she did, and thus unleased all the world's evils, like hunger, sorrow, greed, etc. She finally slammed the box closed, successfully saving Hope, the only thing that makes all these trials bearable.
Pheobe Titaness who became the mother of Leto (mother of the divine twins Artemis and Apollo, both of whom took on the appellation at times: Artemis Phoebe and Apollo Pheobus)
Janus The two-faced Roman god of transitions: bridges, doors, coming-of-age, beginnings and endings. We get the word January from him.

Helene An Amazon warrior who was fated to meet Achilles in battle. After she wounded him, he plunged a sword into her breast and fell in love with her at the same time. Achilles is an idiot like that.

Erriapo
Albiorix Means "king of the world," and is another name for  the ancient Gallic god Teutates. He was god of  war, fertility, and wealth (pretty much everything there is to be god of), and approved to human sacrifices. Equivilent to Mars/Ares.
Suttung A Norse Giant who stole the mead of poetry from the dwarves that made it from Kvasir's blood, and hid it in a mountain. Odin heard his boasting and managed to get it all for himself.
Uranus the god of the sky; the first son of Gaea, as well as her husband. They produced the Titans, the Giants, and other pre-pantheon gods and creatures. All of Uranus's moons are named for Shakespeare characters, which is too bad, because there were plenty of Titans and monsters associated with him that could have been used.
