C/1935 Q1 Van Biesbroeck
more info
Comet C/1935 Q1 was discovered on 21 August 1935, about 7.5 months before perihelion passage, and soon a few prediscovery images were found (taken at Union Observatory in South Africa) extending arc to 3 July 1935; comet was last seen on 26 January 1938 [Kronk, Cometography: Volume 4].
This comet made two close approaches to the Earth, on 4 August 1935 (3.70 au) and on 6 August 1936 (3.62 au).
Solution given here is based on data spanning over 2.30 yr in a range of heliocentric distances from 4.83 au through perihelion (4.04 au) to 6.06 au.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system; however, they lead to escape the comet from the solar system on a hiperbolic orbit (see future barycentric orbit).
