Reluctantly Mortal

Commission for @foxgirlchorix of all of Jupiter's Moons, as seen from the cloud tops, with the correct relative apparent sizes for each of the Galilean moons and the inner four asteroid moons.

The sky is blue due to Rayleigh scattering in Jupiter's hydrogen-helium atmosphere. The tan clouds are made of Ammonia ice crystals, and the brown clouds are made of Ammonium Hydrosulfide ice crystals.

Note: The scale is exaggerated--for comparison, Io's apparent size is about the same as the Moon as seen from the Earth, and an alignment of all of the moons like this is impossible (because whenever two of the inner three Galilean moons are aligned with Jupiter, the other is on the opposite side of the sky, due to the 1:2:4 orbital resonance.)
