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]

Machholz (1989), "Comet Corner", Journal of the Association of Lunar and Planetary Observers, 33 (1): 25–28, 26, Bibcode:1989JALPO..33...25M, A hyphen (-) is used in a comet's name only to separate the discoverers. Thus, when sometimes the discover has a double name, the hyphen is dropped from the comet's name in order to show that there was only one discoverer. For example, in 1986 Stephen Singer-Brewster discovered a comet. It is known as "Comet Singer Brewster."
