C/2016 E1 PANSTARRS
more info
Comet C/2016 E1 was discovered on 3 March 2016 with Pan-STARRS 1 telescope (Haleakala), that is about 1.3 yr before its perihelion passage. This comet was observed until 1 January 2020.
Comet had its closest approach to the Earth on 10 April 2017 (7.345 au), almost 2 months before its perihelion passage.
The preferred solution given here is based on data spanning over 3.83 yr in a range of heliocentric distances: 8.62 au – 8.18 au (perihelion) – 9.90 au.
This Oort spike comet suffers rather small planetary perturbations during its passage through the planetary system; however, these perturbations likely lead to escape the comet from the planetary zone on a hyperbolic orbit (see future barycentric orbits).
