C/1974 V1 van den Bergh
more info
Comet C/1974 V1 was discovered on 11 November 1974, 3.2 months after perihelion passage, and was last seen on 31 October 1976 [Kronk and Meyer, Cometography: Volume 5].
The comet made its closest approach to the Earth on 28 October 1974 (5.11 au), two weeks before discovery.
Solution given here is based on data spanning over 1.97 yr in a range of heliocentric distances from 6.06 au to 8.19 au.
This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system that lead to a more tight future orbit (see future barycentric orbit).
