C/2017 K5 PANSTARRS
more info
Comet C/2017 K5 was discovered on 27 May 2017 with Pan-STARRS 1 telescope (Haleakala), that is almost 3 years before its perihelion passage. This comet was observed until 9 July 2020.
Comet will have its closest approach to the Earth on 2 July 2020 (6.688 au), a bit more than a 3 months after its perihelion passage.
The preferred solution given here is based on pre-perihelion data spanning over 3.12 yr in a range of heliocentric distances from 9.90 au – 7.68 au (perihelion) – 7.71 au.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system that likely lead to escape the comet from the planetary zone on a hyperbolic orbit (see future barycentric orbits).
