C/2000 K1 LINEAR
more info
C/2000 K1 was discovered on 26 May 2000 by the LINEAR as a cometary object [IAUC 7430, 2000 May 26]. Positional observations of this comet were next linked with pre-discovery measurements of two asteroidal objects observed by LINEAR in 1999 (1999 LW24 = 1999 NF13) from May to July 1999, and in May 2000 [IAUC 7431, MPEC 2000-K26, 27, 29].
This comet made its closest approach to the Earth on 15 June 1999 (5.387 au), six months before its perihelion passage.
Solution given here is based on data spanning over 2.2 yr in a range of heliocentric distances: 6.44 au – 6.276 au (perihelion) – 7.51 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).
