C/2010 R1 LINEAR
more info
Comet C/2010 R1 was discovered on 4 September 2010 and next observed 3.6 yr in a range of heliocentric distances: 7.15 au – 5.621 au (perihelion) – 7.40 au. At the moment of discovery, it was 1.7 yr before perihelion passage (see figure).
Comet had its closest approach to the Earth on 10 May 2012 (4.694 au, eight days before perihelion).
This Oort spike comet suffers tiny planetary perturbations during its passage through the planetary system.
