C/2014 M1 PANSTARRS
more info
Comet C/2014 M1 was discovered on 24 June 2014 with Pan-STARRS 1 telescope (Haleakala), that is more than a year before its perihelion passage. This comet was rather rarely observed during four oppositions until 7 March 2017.
Comet had its closest approach to the Earth on 17 June 2015 (4.603 au), more than two months before perihelion passage.
Solution given here are based on data spanning over 2.70 yr in a range of heliocentric distances: 6.37 au – 5.577 au (perihelion) – 6.86 au.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system; these perturbations lead to a more tight future orbit (see future barycentric orbits).
