→Ring system: Shoemaker-levy
== Ring system ==
== Ring system ==
Jupiter does have a ring, consisting of three components, called the halo, the main ring, and the gossamer ring. This ring lies entirely within the region occupied by the four innermost moons, and probably derives its substance from escaping dust from the two innermost moons, [[Metis]] and [[Adrastea]]. The average size of the ring particles is 10 microns, comparable in size to the particles in [[tobacco]] smoke.<ref name=nasa4>Harvey, Samantha.

==Shoemaker-Levy==
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 collissions, at least 21 seperate fragments with a size of up to 2 kilometers hit jupiter, leaving scars in its atmosphere larger than sevearal Earths.
