Comet Mrkos, formally known as C/1957 P1 (old style 1957d), was a non-periodic comet discovered in 1957 by Antonín Mrkos. It was one of two bright comets that had their perihelion in 1957, the other being Comet Arend–Roland. Its peak magnitude was estimated to be around 1[2] and it has been characterised as a great comet.[3]
