C/2014 W10 PanSTARRS
more info
Comet C/2014 W10 was discovered on 25 November 2014 with the Pan-STARRS 1 telescope (Haleakala), that is more than one year before its perihelion passage. This comet was observed only 12 days and its orbit was extremaly uncertain until the calculations presented by Królikowska and Dybczyński (2018) Fortunately later, a set of three measurement going about one year back (from 24 November of 2013) was found (gathered using the same telescope).
Thus, the GR solution given here is based on pre-perihelion data span over 1.04 yr in a range of heliocentric distances from 9.14 au to 8.12 au.
Comet had its closest approach to the Earth on 9 November 2015 (6.90 au), more than 3 months before its perihelion passage.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system; and its future orbit have semimajor axis longer than 10,000 au.
