PRESENTATION OUTLINE
The size and mass of the original body and the individual fragments is as of this writing still highly uncertain. The estimates range from 2 to 10 km in diameter for the original body and from 1 to 3 km for the largest fragments.
The orbital period of this comet is 10 years.
Comet Shoemaker-Levy 9 was discovered by Eugene and Carolyn Shoemaker and David Levy in 1993. Shortly after its discovery it was determined to be in a highly elliptical path near Jupiter and on a collision course. It was difficult to calculate its orbit prior to its 1992 pass near the giant planet.
In 1992, SL 9 passed by Jupiter within the Roche limit. It was broken into at least 21 separate fragments which were dispersed several million kilometers along its orbit.
