C/2019 F1 ATLAS-Africano
more info
Comet C/2019 F1 was discovered on 28/29 March 2019, more than 2 yr before its perihelion passage. Later a series of pre-discovery observations were found going backto 8 February 2019. In the moment of orbit determination, this comet was still observed.
Solutions (GR and NG) given here span over 4.01 yr in a range of heliocentric distances: 7.96 au – 3.60 au (perihelion) – 6.24 au; also orbit based on pre-perihelion data and post-perihelion data are presented.
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).
