63P/Wild is a periodic comet in our Solar System with a current orbital period of 13.21 years.

It was first detected by Paul Wild at the Zimmerwald Observatory of the Astronomical Institute of Bern, Switzerland on a photographic plate exposed on 26 March 1960, who estimated its brightness at a magnitude of 14.3. Its elliptical orbit was then calculated to have an orbital period of 13.17 years. [1]

Its predicted reappearance in 1973 was observed by Elizabeth Roemer of the U.S. Naval Observatory, Flagstaff, Arizona at a magnitude of 17.5. Although not found in 1986 it was rediscovered in 1999 with a magnitude of around 12.

The 2013 return was moderately favourable with magnitude again around 12.
