Type: Periodic Perihelion date: 3 August 2023 Perihelion distance (q): 2.9 Aphelion distance (Q) : 7,289 Period (years): 220,133 Eccentricity (e): 1.00 Inclination (i): 52.0 JPL orbit diagram COBS lightcurve The Bok NEO survey with the Kitt Peak 2.25 m reflector discovered a 20th magnitude object on 26 October 2022. Follow-up observations with the Steward Observatory 1- m reflector at Mt Lemmon suggested cometary activity and this was confirmed by other astrometrists. There were prediscovery observations in January, February and March 2022 by PanSTARRS.
