332P/Ikeya–Murakami (P/2010 V1) is a short-period comet with period of approximately 5.4 years first identified independently by the two Japanese amateur astronomers Kaoru Ikeya and Shigeki Murakami on November 3, 2010. As 332P/Ikeya–Murakami only approaches within 1.57 AU of the Sun, roughly Mars distance from the Sun, the fragmentation events may be a result of rapid rotation. The comet was last observed in October 2020 as during the 2021 perihelion passage the comet was only 7 degrees from the Sun. The comet will next come to perihelion in January 2027 when it will have a solar elongation o

255P/Levy, formerly P/2006 T1 and P/2011 Y1, is a Jupiter-family comet with an orbital period of 5.25 years. It last came to perihelion (closest approach to the Sun) on 14 January 2012. During the 2006 passage the comet achieved an apparent magnitude of ~9.5. Levy (PK06T010) was believed to have been recovered on 3 June 2011 at magnitude 19.8, but other observatories were unable to confirm a recovery. It was most likely a false positive because of large residuals. Levy was recovered on 17 December 2011 at magnitude 19.8, and given the second designation 2011 Y1. It was then numbered.
