The comet showed a coma and tail. The comet was at perihelion at 1.5 au in August 2010 and has a period of 5.7 years. An apparently asteroidal object of 21st magnitude was discovered by PanSTARRS on 10 April 2016. It was linked to earlier observations and given a minor planet designation. Further PanSTARRS images taken in early June suggested that it was likely to be a comet. After their report had been received by the MPC, the MPC received a report from Erwin Schwab on the recovery of 2010 N1 (P/WISE) and he later noted the identity with the asteroid. The comet made a close (0.52 au) approach to Jupiter in June 2013, which increased the perihelion distance from 1.49 au to its current value and also slightly lengthened the period.
