215P/NEAT (0215P)

Type: Periodic Perihelion date: 18 November 2019 Perihelion distance (q): 3.6 Aphelion distance (Q) : 5.0 Period (years): 9.0 Eccentricity (e): 0.17 Inclination (i): 10.6 JPL orbit diagram COBS lightcurve 215P/NEAT = 2002 O8 = 2009 B5 K. Lawrence, Jet Propulsion Laboratory, reported the discovery of a 17th magmitude comet with nuclear condensation of diameter about 6" and a tail extending about 10" to the west on NEAT images obtained on 29 July 2002. Confirmation of cometary activity was reported by A. C. Gilmore and P. M. Kilmartin on CCD images taken with the 0.6-m reflector at Mt John University Observatory on 4 August. Prediscovery observations were identified in NEAT data from 16 July, LINEAR data from 5 July and Spacewatch data from 22 May and 11 June 2001.
