Comet 471P/LINEAR-Fazekas (astro.vanbuitenen.nl)

Discovery:

object discovered by LINEAR on 2010 December 31.29 and designated as 2010 YK3

Recovery:  [CBET 5292 ]

    Jacqueline Fazekas reported in June that she had noted cometary activity in an object discovered with the 1.5-m reflector of the Mt Lemmon Survey on 2023 May 24.44. The activity was confirmed by several other observers and reported on the comets-ml on September 6. It was linked to an object discovered by LINEAR on 2010 December 31.29 and designated as 2010 YK3 and there was a Spacewatch image from 1996 June.  The MPC later confirmed the cometary nature [MPEC 2023-R42, 2023 September 8]. The comet is at perihelion in December at 2.1 au and has a period of 13.6 years. It has a Jupiter MOID of 0.3 au, with an approach to 0.9 au in 1995 May and one to 0.6 au in 2039 February.
