C/2016 C1 PANSTARRS
more info
Comet C/2016 C1 was discovered on 12 February 2016 with Pan-STARRS 1 telescope (Haleakala), that is a week before its perihelion passage. This comet was observed until 24 May 2020.
Comet had its closest approach to the Earth on 5 March 2016 (7.572 au), about 2 weeks after its perihelion passage.
The preferred solution given here is based on data spanning over 4.28 yr in a range of heliocentric distances: 8.46 au – 8.46 au (perihelion) – 12.3 au.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system; however, these perturbations likely lead to escape the comet from the planetary zone on a hyperbolic orbit (see future barycentric orbits).
