C/2020 N1 PanSTARRS
more info
Comet C/2020 N1 was discovered on 3 July 2020, about 8.5 months before its perihelion passage, later a single pre-discovery observation was found from 1 July 2020. This comet was observed to 14 April 2021.
Solutions given here (NG and GR) are based on data span over 0.786 yr in a range of heliocentric distances: 3.55 au – 1.32 au (perihelion) – 1.41 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.
