C/2011 F1 LINEAR
more info
Comet C/2011 F1 was discovered on 17 March 2011 with Lincoln Laboratory Near-Earth Asteroid Research project; that is about a year and 10 months before its perihelion passage. The comet was observed until 7 August 2014.
Comet had its closest approach to the Earth on 6 April 2013 (2.560 au), about 3 months after its perihelion passage.
Solutions given here are based on data spanning over 3.39 yr in a range of heliocentric distances: 6.99 au – 1.819 au (perihelion) – 6.30 au.
This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system; these perturbations lead to a more tight future orbit (see future barycentric orbits).
