In 1994, scientists were able to witness fragments of the comet Shoemaker-Levy 9 collide with Jupiter. These collissions laster for 6 days, starting on July 16th of that year, and was the first cosmic collission to be observed. During the impacts, at least 21 seperate fragments with a size of up to 2 kilometers hit Jupiter, leaving scars in its atmosphere larger than sevearal Earths.

Jupiter's sidereal day is less than ten Earth hours long. If Jupiter formed simply as an accretion aggregate of the [[nebula hypothesis|solar nebula]], then it should not have acquired such tremendous angular momentum. The problem involves not merely the short sidereal day but also Jupiter's tremendous mass.
