Also known as Comet Ikeya–Murakami
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

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 of 100 degrees.
== Observational history == Ikeya identified the comet using a 25-centimeter (10-inch) reflector at 39×, while Murakami used a 46 cm (18-inch) reflector at 78×. Photographic confirmation of the comet was obtained by Ernesto Guido and Giovanni Sostero using a Global-Rent-a-Scope (GRAS) telescope in New Mexico. Both Ikeya and Murakami discovered the comet using manual observation through optical telescopes. Such visual discoveries have become rare in recent years.
