C/2010 S1 LINEAR
more info
Comet C/2010 S1 was discovered on 21 September 2010 and next observed almost continuously by 4.8 yr in a range of heliocentric distances: 8.85 au – 5.900 au (perihelion) – 8.02 au. At the moment of discovery, it was two years and eight months before perihelion passage (see figure).
Comet had its closest approach to the Earth on 4 August 2013 (5.205 au, 2.5 months after perihelion).
This Oort spike comet suffers tiny planetary perturbations during its passage through the planetary system.
