129P/Shoemaker–Levy, also known as Shoemaker–Levy 3, is a periodic comet in the Solar System. It fits the definition of an Encke-type comet with (TJupiter > 3; a < aJupiter),[4] and is a quasi-Hilda comet.[5]

This comet should not be confused with Comet Shoemaker–Levy 9 (D/1993 F2), which spectacularly crashed into Jupiter in 1994.
