466P/PANSTARRS (0466P)

TRY AGAIN 2030

Type: Periodic Perihelion date: 3 May 2023 Perihelion distance (q): 2.2 Aphelion distance (Q) : 5.9 Period (years): 8.1 Eccentricity (e): 0.47 Inclination (i): 12.2 JPL orbit diagram COBS lightcurve 466P/PanSTARRS = 2015 T3 = 2023 M3 A 21st magnitude comet was discovered in PanSTARRS 1 images taken with the 1.8m Ritchey-Chretien on 13 October 2015. The comet is one of those suspected to have undergone nuclear splitting (Marcos & Marcos link it to 10P/Tempel). The comet was recovered at 19th magnitude on 26 June 2023, in images taken with the 1.5-m reflector of the Mt Lemmon Survey. The comet was at perihelion at 2.2 au in 2023 May and has a period of 8.12 years. The comet passed 0.63 au from Jupiter on 24 August 2003 and will pass 0.28 au from Jupiter on 24 December 2025, which will slightly increase the perihelion distance.
