C/2019 G4 PanSTARRS
more info
Comet C/2019 G4 was discovered on 9 April 2019, about 7 months after its perihelion passage. Later a two pre-discovery observations were found from 24 July 2018, these two measurements are the only data taken before perihelion passage.
Solution given here span over 2.30 yr in a range of heliocentric distances: 5.87 au – 5.86 au (perihelion) – 7.99 au.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system that lead to a more tight future orbit (see future barycentric orbit).
