C/2010 D3 WISE
more info
C/2010 D3 was discovered in images from the Wide-field Infrared Survey Explorer (WISE) satellite on 26 February 2010.
This comet made its closest approach to the Earth on 7 June 2010 (4.070 au), about 3 months before perihelion passage (see figure).
Solution given here is based on data spanning over 3.3 yr in a range of heliocentric distances: 4.54 au – 4.248 au (perihelion) – 8.80 au.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system that lead to a more tight future orbit (see future barycentric orbit).
