Although Jupiter would need to be about 75 times as massive to fuse hydrogen and become a star, the smallest red dwarf is only about 30 percent larger in radius than Jupiter. [Wikipedia]

The Jupiter Zoo
What an amazing year! 2011 was a very productive one, offering our astronomy community numerous chances to capture the planets and especially the biggest one; Jupiter! Often, the atmospheric conditions were good enough to make high resolution planetary photography possible even from the backyard!
This is a short video clip of Jupiter on Sept. 26th, 2011 at 20:54 GMT, one month before its opposition. All photos have been taken at 3860mm focal length using a TIS DBK21 color camera on an old Dall Kirkham cassegrain telescope.here. You can easily detect Jupiter's Great Red Spot, a storm having almost the same diameter as Earth. [Wikipedia]
The shadow of Jupiter's icy moon Europa can be detected as a dark spot on some of the images, an evidence of a Sun eclipse on Jupiter. However, this is something occuring frequently.
