Comet Mellish, also known formally as C/1915 C1, is one of five comets discovered by American astronomer John E. Mellish. It is a hyperbolic 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 the June Lyrids meteor shower, which was first discovered in 1966.[6][7]
