Final answer:
The incorrect pairing is Jupiter - Titan, as Titan is a moon of Saturn, not Jupiter. Jupiter's largest moon is Ganymede.
Step-by-step explanation:
The question seeks to identify which of the following moons is not correctly paired with its planet. Here is the correct pairing for each mentioned celestial body:
- Mars - Its moons are Phobos and Deimos, not listed here.
- Jupiter - Its largest moons are the Galilean moons: Io, Europa, Ganymede, and Callisto.
- Saturn - Its largest moon is Titan, and it also possesses other notable moons including Enceladus.
- Neptune - Its largest moon is Triton.
Therefore, the pairing that is not correct is Jupiter - Titan. Titan is in fact a moon of Saturn, not Jupiter. Jupiter's largest moon is Ganymede. Saturn's moon Titan is particularly interesting because of its substantial atmosphere and surface lakes of liquid hydrocarbons, while Enceladus is known for its active geysers of water. Neptune's moon Triton is unique for its retrograde orbit and its very thin atmosphere, with active eruptions observed by the Voyager spacecraft in 1989.
