C/2014 R3 PANSTARRS
more info
Comet C/2014 R3 was discovered on 6 September 2014 with Pan-STARRS 1 telescope (Haleakala), that is almost two years before its perihelion passage. This comet was observed until the end of 2019, and is still observable.
Comet had its closest approach to the Earth on 24 February 2017 (6.829 au), about 6.5 months after its perihelion passage.
Solution given here is based on data spanning over 3.47 yr in a range of heliocentric distances: 8.51 au – 7.275 au (perihelion) – 8.11 au (25 February 2018).
This marginally Oort spike comet suffers slight planetary perturbations during its passage through the planetary system; these perturbations lead to a more tight future orbit (see future barycentric orbits).
