Another very significant ધૂમકેતુary disruption was that of [[ધૂમકેતુ Shoemaker-Levy 9]], which was discovered in [[1993]]. At the time of its discovery, the ધૂમકેતુ was in ભ્રમણકક્ષા around ગુરુ, having been captured by the planet during a very close approach in [[1992]]. This close approach had already broken the ધૂમકેતુ into hundreds of pieces, and over a period of 6 days in July [[1994]], these pieces slammed into ગુરુ's વાતાવરણ — the first time astronomers had observed a collision between two objects in the સૂર્યમંડળ.{{hnote|Kronk, 'D/1993 F2 Shoemaker-Levy 9'}} However, it has been suggested that the object responsible for the [[Tunguska event]] in [[1908]] was a fragment of ધૂમકેતુ Encke.
