118P/Shoemaker–Levy (also known as periodic comet Shoemaker–Levy 4) is a comet discovered by astronomers Carolyn and Eugene M. Shoemaker and David Levy.[1]
During the 2010 apparition the comet became as bright as apparent magnitude 11.5.[4]
The comet nucleus is estimated to be 4.8 kilometers in diameter.[1]
On December 3, 2015, comet Shoemaker–Levy 4 will pass 0.0442 AU (6,610,000 km; 4,110,000 mi) from asteroid 4 Vesta.[5]
This comet should not be confused with Comet Shoemaker–Levy 9 (D/1993 F2) which spectacularly crashed into Jupiter in 1994.
