C/2015 LC2 PANSTARRS
more info
Comet C/2015 LC2 was discovered on 7 June 2015 with Pan-STARRS 1 telescope (Haleakala), that is about a month after its perihelion passage.This comet was observed until 17 August 2018.
Comet had its closest approach to the Earth on 8 May 2015 (4.939 au), a week after its perihelion passage.
Solution given here is based on data spanning over 2.78 yr in a range of heliocentric distances from 5.90 au to 9.97 au.
This comet suffers insignificant planetary perturbations during its passage through the planetary system; have original semimajor axis shorter than 10000 au.
