176P/LINEAR (0176P)

Type: Periodic Perihelion date: 23 November 2022 Perihelion distance (q): 2.6 Aphelion distance (Q) : 3.8 Period (years): 5.7 Eccentricity (e): 0.19 Inclination (i): 0.2 JPL orbit diagram COBS lightcurve Whilst monitoring members of the Themis familly of asteroids for signs of cometary activity, H H Hsieh and Dave Jewitt of the University of Hawaii imaged asteroid 118401. Images taken on 26 November 2005 with the Gemini North telescope showed a tail 7" long, and confirming images were taken in December. The asteroid was found by LINEAR. In June 2006 the Committee on Small Bodies Nomenclature agreed to name and number the comet, although the asteroidal designation will be used for archiving any astrometry.
