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 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).
