C/2020 H6 ATLAS
more info
Comet C/2020 H6 was discovered on 22 April 2020, about 1.3 yr before its perihelion passage. In the moment of orbit determination, this comet was still observed.
Solutions (GR and NG) given here are based on data span over 3.16 yr in a range of heliocentric distances: 6.22 au – 4.70 au (perihelion) – 6.71 au.Orbits based on pre-perihelion and post-perihelion data independently were also obtained.
This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system that lead to a significantly more tight future orbit (semimajor axis of about 2,000 au).
