TRY AGAIN 2039

Type: Periodic Perihelion date: 11 March 2025 Perihelion distance (q): 1.6 Aphelion distance (Q) : 10.6 Period (years): 15.1 Eccentricity (e): 0.73 Inclination (i): 14.8 JPL orbit diagram COBS lightcurve Atlas 496P/Hill = 2010 A3 = 2024 S3 Rik Hill discovered a 17th magnitude comet on 8 January 2010 during the Catalina Sky Survey with the 0.68m Schmidt. The comet was accidently recovered by PanSTARRS on 7 October 2024 and placed on the PCCP as P120uko. Sam Deen spotted that this was a recovery and not a new comet. There were additional images taken before 7 October. There will be a distant encounter with Jupiter in 2042 that will reduce the period to 14.5 years and the perihelion distance to 1.5 au. The Jupiter MOID is 0.10 au.
