C/2020 K8 Catalina-ATLAS
more info
Comet C/2020 K8 was discovered on 25 May 2020, about 3.5 months before its perihelion passage and was observed to 6 April 2021.

Solutions given here (NG and GR) are based on data span over 0.866 yr in a range of heliocentric distances: 2.18 au – 0.475 au (perihelion) – 3.40 au.

This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system that lead to escape the comet from the solar system on hyperbolic barycentric orbit.
