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 AU from the Sun.[9]
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]
