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 3.3 AU e6km unit from the Sun.IAUC_5391 The primary nucleus is 5.6 km mi in diameter and was last observed in 2022.jpl1 Fragment B has not been observed since 2006.jpl2 As of epoch 2022, fragment B takes 21 days longer to orbit the Sun.Horizons-B-20220121 The companion is not expected to survive its next perihelion passage.IAUC_5391 +Difference in perihelion date for fragment A+B Year Horizonsdifference 2005 1 day 2020 18 days 2034 43 days See also 74P/Smirnova–Chernykh References B.
