Sign in to saveAlso known as 1977l Chernykh, 1978 IV Chernykh, 1991o Chernykh, 1992 II Chernykh, 101P/Chernykh - A, 101P/Chernykh - B
101P/Chernykh is a periodic comet which was first discovered on 19 August 1977, by Nikolaj Stepanovich Chernykh. This comet is orbiting the Sun at a distance of 5.8 AU with an eccentricity of 0.60 and an orbital period of 14 years. The elliptical orbit will bring it as close as 2.35 AU and as far as 9.28 AU from the Sun. It will next come to perihelion (closest approach to the Sun) in 2034. The orbital plane is inclined at an angle of 5.05° to the plane of the ecliptic.

101P/Chernykh is a periodic comet which was first discovered on 19 August 1977, by Nikolaj Stepanovich Chernykh. This comet is orbiting the Sun at a distance of 5.8 AU with an eccentricity of 0.60 and an orbital period of 14 years. The elliptical orbit will bring it as close as 2.35 AU and as far as 9.28 AU from the Sun. It will next come to perihelion (closest approach to the Sun) in 2034. The orbital plane is inclined at an angle of 5.05° to the plane of the ecliptic.
In April 1991, the comet was observed to split in two. Zdenek Sekanina, from JPL, concluded that the comet split at a distance of from the Sun. The primary nucleus is in diameter and was last observed in 2022. Fragment B has not been observed since 2006. As of epoch 2022, fragment B takes 21 days longer to orbit the Sun. The companion is not expected to survive its next perihelion passage.
