All of Jupiter’s moons can be considered to be at the same distance from the Sun. Do they have the same surface temperatures?

| We assume that the satellites have no internal energy sources, no atmospheres, and the radiation of Jupiter can be neglected. Obviously, in this case the albedo A will be the main factor determining the surface temperature. The temperature estimate follows from the relation T ^ 4 = (1 -A) E, where T is the surface temperature; o – Stefan – Boltzmann constant; E – illumination at the distance of Jupiter. Based on the above, the temperature of Amalthea and Io should be higher than that of Ganymede and Europa. Io also has a noticeably higher temperature due to strong tidal deformations.
