Ganymede

From Memory Alpha, the free Star Trek reference

Ganymede is the third Galilean moon of Jupiter, fifth planet in the Sol system. It is the largest moon in the system and is named after the cup-bearer of the Greek gods in Terran mythology.

In the 23rd century, Montgomery Scott of the Federation starship USS Enterprise mentioned a mysterious "green drink" he found on Ganymede, and later shared with the Kelvan Tomar. (TOS: "By Any Other Name")
