C/2020 K6 Rankin
more info
Comet C/2020 K6 was discovered on 26 May 2020, about 1.3 yr before its perihelion passage and was observed to 25 June 2023.

Solution given here is based on data span over 3.08 yr in a range of heliocentric distances: 6.76 au – 5.87 au (perihelion) – 7.40 au.

This Oort spike comet suffers tiny planetary perturbations during its passage through the planetary system that lead to bit tight future orbit.
