C/2001 K3 Skiff
more info
Comet C/2001 K3 was discovered on 22 May 2001 by Brian A. Skiff during LONEOS project, that is a month after its perihelion passage. It was observed until 12 October 2001.
Comet had its closest approach to the Earth on 15 July 2001 (2.266 au), less than 2 months after discovery.
Solution given here is based on data spanning over 0.392 yr in a range of heliocentric distances from 3.07 au to 3.49 au.
This Oort spike comet suffers notable planetary perturbations during its passage through the planetary system; these perturbations lead to a significantly more tight future orbit with semimajor axis of about 1,500 au.
