105P/Singer Brewster is a periodic comet in our solar system. Its name is unusual: co-discovered comets bear the names of the co-discoverers linked by hyphens (e.g. Shoemaker-Levy 9, Swift-Tuttle, etc.). But the single discoverer in this case bears a hyphenated name (Stephen Singer-Brewster), so the comet's name replaces the hyphen by a space. It was discovered in 1986, and received the name of 1986d under the old naming system.[4]
Since 105P/Singer Brewster only comes within 2 AU of the Sun,[5] during the 2012 perihelion passage it is only expected to brighten to about apparent magnitude 17.[6]
The comet nucleus is estimated to be 2.2 kilometers in diameter.[5]
The orbit was altered significantly in August 1976 when it passed within 0.376 AU of Jupiter and will be altered again in August 2059.[7][8]
