Not to be confused with the much better-known C/1973 E1 (Kohoutek), 75D is a repeat visitor to the inner Solar System, with a period of about seven years. It was placed on the discovery orbit when it passed 0.143 AU (21,400,000 km; 13,300,000 mi) from Jupiter on 28 July 1972.[2][3] Apparitions have been dim, with the brightest being in 1988 at about apparent magnitude 13.[2] It was not seen in 1994, 2000, 2007, nor on its last predicted return in 2014. The comet has been estimated to be 4.6 kilometres (2.9 mi) in diameter.[3]
This comet was last observed by Mauna Kea on 19 May 1988.[1] The Minor Planet Center has given the comet a "D/" designation as the comet is believed to be lost.[1][4] The comet is calculated to come to opposition in October 2020 in the constellation of Pisces.
