C/2011 Q1 PANSTARRS
more info
Comet C/2011 Q1 was discovered on 20 August 2011 by Pan-STARRS 1 telescope (Haleakala), that is about 1.5 month after its perihelion passage. Soon, C/2011 Q1 was found on earlier images taken on 17 August 2011 with the Pan-STARRS 1 survey. It was occasionally observed less than a year.
Comet had its closest approach to the Earth on 21 August 2011 (6.046 au), a day after its discovery.
Solution given here is based on data spanning over 0.86 yr in a range of heliocentric distances from 6.79 au to 7.18 au.
This comet have orignal semimajor axis shorter than 10000 au; it suffers a tiny planetary perturbations during its passage through the planetary system that lead to a more tight future orbit. (see future barycentric orbit).
