65P/Gunn is a periodic comet in the solar system which has a current orbital period of 6.79 years.
It was discovered on 11 October 1970 by Professor James E. Gunn of Princeton University using the 122-cm Schmidt telescope at the Palomar Observatory. It had a low brightness of magnitude 16 plus which improves to 12 under favourable conditions.
The comet is a short-period comet, orbiting the Sun every 6.79 years inside the main asteroid belt between the orbits of the planets Mars and Jupiter.[2]
On 4 February 1970 the comet passed 0.015 AU (2,200,000 km; 1,400,000 mi) from Ceres.[3]
