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).
NG orbit is possible to obtained using the full data arc; however uncertainties of NG parameters are notable, especially for A2 (see solutions ac and bc differing only in data weighting).
This Oort spike comet suffers a tiny planetary perturbations during its passage through the planetary system.

Upper panel: Time distribution of positional observations with corresponding heliocentric (red curve) and geocentric (green curve) distance at which they were taken. The horizontal dotted line shows the perihelion distance for a given comet whereas vertical dotted line — the moment of perihelion passage.
Middle panel(s): O-C diagram for a given solution (sometimes in comparison to another solution available in CODE), where residuals in right ascension are shown using magenta dots and in declination by blue open circles.
Lowest panel: Relative weights for a given data set(s).
