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, Helin-Roman-Alu 1, 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.

Since 105P/Singer Brewster only comes within 2 AU of the Sun,[3] during the 2012 perihelion passage it is only expected to brighten to about apparent magnitude 17.[4]

The comet nucleus is estimated to be 2.2 kilometers in diameter.[3]
