Answer 4

But, why those names?

Jupiter:
In Greek Mythology, Zeus became the top god after defeating his father Chronos and the Titans.

When Greeks descendants founded Rome, they took the existing (not yet but soon to become) Latin gods and associated them to their Greek gods.

Iuppiter (same etymology as Zeus: "Dyaus Pitar", old Indo-European sky god) was associated with Zeus. In the Latin form, the genitive (possessive case in grammar) is ioves which gives us the adjective Jovian (and the exclamation "By Jove"). Jupiter did have a pre-Latin mythology but it was pretty well overwritten with that of Zeus.

Io : According to the legend, she was a priestess of Hera (wife of Zeus). Zeus secretly loved her. The jealous Hera found out and wanted to kill her; Zeus changed her into a cow so that Hera would not find her (in some versions, Hera changes her into a cow).

Europa: a Phoenician woman (princess), daughter of Oceanus and Tethys. A Cretan version of a story similar to Io's: Zeus fell in love with Europa, To seduce her, he changed himself to a bull in order to get close to her without raising suspicion. She climbed on the back of the bull which immediately took off and took her to the island of Crete. The constellation Taurus (the Bull) would be an image created in the sky by Zeus to remember this event.

Ganymede: Trojan prince, son of Tros and Callirrhoe. Zeus took him to Olympus to become a servant of the gods. They all liked him -- except Hera (this would explain why she abandoned the Trojans during the Trojan War. Zeus took the form of an eagle to take Ganymede (constellation Aquila, the Eagle).

Callisto: a nymph of Arcadia. Zeus loved her and she had a child. Hera changed her and her child into a Bear and her cub. Callisto was killed by Artemis (tricked by Hera -- some myths say that Zeus had disguised himself as Artemis in order to seduce Callisto). When Zeus found out, he put Callisto in the sky (Ursa Major) along with her cub (Ursa Minor); the still jealous Hera inserted the dragon (Draco) between them so that Callisto is stuck with foever circling the sky, trying to get around the dragon to get to her cub.

Amalthea: Chronos had heard that one of his children would overthrow him one day. Every time a child was born, Chronos would kill it by eating it. When Zeus was born, his mother put a rock in his place in the crib and Chronos ate the rock instead (not much of a chewer, I guess). Meanwhile, baby Zeus was hidden in Crete where, according to some versions, he was fed by a goat, in others by a goat herder named Amalthea. In the goat version, one of the horns of the goat fell off and filled itself with food (the horn-of-plenty -- cornucopia) or became the vessel (rhyton) from which Zeus drank as a child.

Himalia: another nymph. Zeus has three children from her.

Elara: Zeus seduced her (he got around quite a bit) and she gave birth to the giant Tityus (I remember him from the "Hercules" cartoons from mumblety-mumble decades ago).

Pasiphae: A cow-goddess. Zeus, in the form of a bull, fell in love with her. In some versions, she became Hera, Zeus's wife. In the non-Hera versions, she gave birth to Asterios (the Minotaur) who was kept in the Labyrinth constructed by Daedalus.

Sinope: Daughter of Asopus and Metope (this made her a niece of Europa). According to what I find, she would have been abducted by Appolo (in a story very similar to many above). I'm not sure why she is in the list of moons, except that Zeus would often impersonate other gods to achieve his ends and Appolo was one of his favorite disguises. It is possible that she had been kidnapped by Zeus in a separate event (prior to her abduction by Appolo) and when her father fought Zeus, the lightning bolts came out.

Lysithea: a sister of Europa. She was also a lover to Zeus.

I'll stop here. The actual stories are far more complex than what I have shown here (and there are often many versions). But you get the drift: they are all somehow associated to the mythology of Zeus.
