C/2014 B1 Schwartz
more info
Comet C/2014 B1 was discovered on 28 January 2014 with Tenagra Observatory near Nogales (U.S.A.), that is about 3.8 yr before its perihelion passage. This comet was observed until the end of 2019, and is still observable.
Comet had its closest approach to the Earth on 23 February 2018 (8.613 au), about 5.5 months after its perihelion passage. Similar close approach to the Earth was at the previous opposition on 11 February 2017 (8.664 au).
Solution given here is based on data spanning over 4.07 yr in a range of heliocentric distances: 11.97 au – 9.557 au (perihelion) – 9.60 au (23 February 2018).
This Oort spike comet suffers extremely slight planetary perturbations during its passage through the planetary system and its semimajor axis will be almost unchanged after leaving the planetary zone (see future barycentric orbits).
