82P/Gehrels is a periodic comet that was discovered on October 27, 1975, by Tom Gehrels at the Palomar Mountain Observatory in California having a faint nuclear brightness of magnitude 17. Calculations based on the early sightings gave an estimated perihelion of 23 April 1975 and an orbital period of 8.11 years. It was observed by J. Gibson on its next predicted apparition in 1984, using the 122-cm Schmidt at Palomar, when he estimated the nuclear brightness at a very faint magnitude 20. It has since been observed in 1993, 2001 and 2010.
