C/1960 M1 Humason
more info
Comet C/1960 M1 was discovered on 18 June 1960, 6.5 months after perihelion passage, and was last seen on 7 June 1961 [Kronk and Meyer, Cometography: Volume 5].
The comet made its closest approach to the Earth on 16 May 1960 (3.91 au), about one month before discovery.
Solution given here is based on data spanning over 0.98 yr in a range of heliocentric distances from 4.56 au to 6.11 au.
This Oort spike comet suffers slight planetary perturbations during its passage through the planetary system but these perturbations can lead to escape of the comet from the solar system.
