105P/Singer Brewster is a periodic comet in the Solar System. It was discovered in 1986, and received the name of 1986d under the old naming system.[1]

Because 105P/Singer Brewster only comes within 2 AU of the Sun,[2] during the 2012 perihelion passage it is only expected to brighten to about apparent magnitude 17.[3]

The comet nucleus is estimated to be 2.2 kilometers in diameter.[2]

The orbit of Comet Singer Brewster was altered significantly in August 1976 when it passed within 0.376 AU of Jupiter and will be altered again in August 2059.[4][5]

The single discoverer bears a hyphenated surname (Singer-Brewster), but co-discovered comets bear the names of the co-discoverers linked by hyphens, e.g. Shoemaker-Levy 9, Swift-Tuttle, etc. In these cases, the IAU either removes one of the parts of the name or replaces the hyphen by a space.[6][7]
