It is also classified as a quasi-Hilda comet.Toth_2006 This comet should not be confused with Comet Shoemaker–Levy 9 (D/1993 F2), which spectacularly crashed into Jupiter in 1994. Physical characteristics The nucleus of Comet Shoemaker–Levy 3 is estimated to have a radius of 1.22 ± 0.1 km mi based on infrared imaging by the Spitzer Space Telescope.Fernandez_2013 Notes "obs_arc" Observation arc from the Minor Planet Center database covering dates from 7 February 1991 until 27 May 2025.
