P/2013 G1 (Kowalski)


Type: Periodic Perihelion date: 10 December 2013 Perihelion distance (q): 3.3 Aphelion distance (Q) : 10.4 Period (years): 18.0 Eccentricity (e): 0.51 Inclination (i): 5.5 JPL orbit diagram COBS lightcurve Richard Kowalski discovered an 18th magnitude comet on 2 April 2013 on images taken during the Mt Lemmon Survey with the 1.5m reflector. This was the 150th comet discovered by the Catalina /Mt Lemmon Sky Survey. The comet made an approach to Jupiter in 1927, and then had a very close approach to within 0.003 au of Saturn in 2001 April. This encounter increased the perihelion distance from around 2 au to its present 3.3 au.
