75D/Kohoutek
Sign in to save75D/Kohoutek is a periodic comet discovered in February 1975, by Luboš Kohoutek. Even on the discovery plate the comet was only apparent magnitude 14. Assuming the comet has not disintegrated the 2020-2021 perihelion passage is only expected to peak around apparent magnitude 20.

75D/Kohoutek is a periodic comet discovered in February 1975, by Luboš Kohoutek. Even on the discovery plate the comet was only apparent magnitude 14. Assuming the comet has not disintegrated the 2020-2021 perihelion passage is only expected to peak around apparent magnitude 20.
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 from Jupiter on 28 July 1972. Apparitions have been dim, with the brightest being in 1988 at about apparent magnitude 13. It was not seen in 1994, 2000, 2007, nor on its last predicted return in 2014. The comet has been estimated to be in diameter.
