Type: Periodic Perihelion date: 24 October 2021 Perihelion distance (q): 3.4 Aphelion distance (Q) : 5.0 Period (years): 8.7 Eccentricity (e): 0.19 Inclination (i): 5.8 JPL orbit diagram COBS lightcurve (323137) = 2003 BM80 = 2003 FV112 Pan-STARRS discovered a 21st magnitude comet on 6 October 2012. Confirmation was made by astrometrists from the T3 group. Archival observations from Pan- STARRS were found from July 2011. The comet was designated as 2012 T1. It was at perihelion at 2.4 AU in September 2012 and has a period of around 5.6 years. It is a Main Belt Comet, with a stable orbit for the period 1900 - 2100. In January 2013 Rob Matson found images of a comet in frames taken by NEAT with the Palomar 1.2m Schmidt on 9 December 2001. This was linked to 2003 BM80, which had been discovered by LONEOS on 31 January 2003 at the Anderson Mesa station, and to the PanSTARRS comet allowing it to be numbered as 282P. Although the comet was numbered, the MPC list does not give it a name. 2012 T1 was recovered on 1 July 2017 with the Gemini South 8.1m reflector. This time it was given the PanSTARRS name and the designation 2017 O3, though not linked to the previously numbered comet. It seems that the original linkage was incorrect and so the PanSTARRS comet was then renumbered as 358P folowing this recovery. The linked orbit for 358P does include the NEAT observations from 2001.
