101P/Chernykh[7] is a periodic comet which was first discovered on August 19, 1977, by Nikolaj Stepanovich Chernykh.[8] It will next come to perihelion (closest approach to the Sun) in 2034.
In 1991, 101P/Chernykh was observed to split. Zdenek Sekanina, from JPL, concluded that the comet split in April 1991, when 3.3
The primary nucleus is 5.6 km (3.5 mi) in diameter and was last observed in 2022.[10] Fragment B has not been observed since 2006.[5] As of epoch 2022, fragment B takes 21 days longer to orbit the Sun.[2]
