C/2013 P3 Palomar
more info
Comet C/2013 P3 was discovered on 9 August 2013 with Palomar Transient Factory survey, that is about 1.3 yr before its perihelion passage. Next, it was found on images taken the day before discovery during the same survey. This comet was observed until 24 June 2018.
Comet had its closest approach to the Earth on 21 September 2014 (7.657 au), about 2 months before perihelion passage.
Solution given here is based on data spanning over 4.88 yr in a range of heliocentric distances: 9.070 au – 8.647 au (perihelion) – 11.42 au.
This Oort spike comet suffers so tiny planetary perturbations during its passage through the planetary system that its semimajor axis will be almost unchanged after leaving the planetary zone.< br>
