C/2002 J5 LINEAR
more info
C/2002 J5 was discovered on 15 May 2002 by the LINEAR as an apparently asteroidal object. Next day, its cometary apperance was reported by M. Tichy and M. Kocer from Klet [IAUC 7904, 2002 May 18]. Later, pre-discovery detections (from August 2001) by LINEAR and AMOS were found.

This comet made its closest approach to the Earth on 19 June 2003 (5.233 au), three months before perihelion.

Solutions given here are based on data spanning over 4.6 yr in a range of heliocentric distances: 7.87 au – 5.727 au (perihelion) – 8.44 au.

This Oort spike comet suffers slight 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).
