Asteroids relabelled as comets


 

Four new comets (asteroids relabelled as...) in MPECs H86, H87, H88 and H90:

H86: P/2017 FL36 (PANSTARRS) -- single apparition in 2017, P=5.01 years, next perihelion in August 2025. Note that it was observed when it was closer to aphelion (~January 2018) than perihelion (June 2015, July 2020), that makes it a strange case.

H87: P/2009 KF37 (unnamed) -- observed in 2001, 2009, every year between 2014 and 2017, and now 2025; P = 8.34 years

H88: C/2012 KA51 (unnamed) -- quasi-parabolic, single apparition in 2012

H90: P/2010 KG43 = P/2010 PT8 (unnamed) -- observed in 2010 and 2023; P = 13.2 years
