Comet Mellish, also known formally asC/1915 C1, is one of five comets discovered by American astronomerJohn E. Mellish. It is ahyperbolic comet that reached perihelion on July 17, 1915. However, just two months earlier,Edward E. Barnard had reported the comet had splitted into three distinct objects in May 12,[4] later increasing to four by May 24.[5] In addition, it is thought that this comet was the parent body of theJune Lyridsmeteor shower, which was first discovered in 1966.[6][7]
