Jupiter rotation

The fast rotation of Jupiter is evident in these two images taken only half an hour apart. Jupiter completes a full rotation in just 9 hours and 50 minutes. The planet is therefore also significantly eccentric, being wider along the equator than from pole to pole.
In these images the solar systems largest moon, Ganymede, is transitting in front of the lover part of Jupiter's disc. Notice the surface details visible on this moon.
