C/2019 L3 ATLAS

Comet C/2019 L3 was discovered on 10 June 2019, about 2.5 yr before its perihelion passage. In the moment of orbit determination, this comet was still observed.

Currently, solutions (GR and NG) given here are based on pre-perihelion data and span over 2.58 yr in a range of heliocentric distances from 8.46 au to 3.56 au.

This is Oort spike comet.
