C/1892 Q1 Brooks
more info
C/1892 Q1 was discovered on 28 August 1892 by William Robert Brooks (Smith Observatory at Hobart College, Geneva, New York, USA), that is about 4 months before its perihelion passage, and it was last seen on 19 July 1893 [Kronk, Cometography: Volume 2].
This comet made its closest approach to the Earth on 12 December 1892 (2.27 au), that is about two weeks before perihelion passage.
Solutions given here are based on data spanning over 0.863 yr in a range of heliocentric distances from 2.11 au through perihelion (0.976 au) to 3.04 au.
This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system; these perturbations lead to a escape the comet from the planetary zone on hypebolic orbit (see future barycentric orbits).
