C/1941 K1 Van Gent
more info
Comet C/1941 K1 was discovered on 27 May 1941 by Hendrik van Gent (), that is about three months before perihelion passage, and the comet was last seen on 18 February 1942 [Kronk, Cometography: Volume 4].
This comet made its closest approach to the Earth on 21 June 1941 (0.603 au), that is almost a month after its discovery. The next close approach to the Earth was on 24 November (0.771 au).
Solution given here is based on data spanning over 0.710 yr in a range of heliocentric distances from 1.759 au through perihelion (0.875 au) to 2.738 au.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system and left the planetary zone on a slightly more tight orbit in comparison to its original barycentric orbit (see future barycentric orbit).
