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.
