'''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. [[Comet Shoemaker–Levy 9|Shoemaker-Levy 9]], [[109P/Swift–Tuttle|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.<ref name=nca/>


Since 105P/Singer Brewster only comes within 2&nbsp;[[Astronomical Unit|AU]] of the Sun,<ref name="jpldata"/> during the 2012 [[Apsis|perihelion]] passage it is only expected to brighten to about [[apparent magnitude]] 17.<ref name="mag2012"/>

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.[4]

Because 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 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.[7][8]

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.[9][10]
