C/2005 K1 Skiff
more info
C/2005 K1 was discovered by Brian A. Skiff on 16 May 2005 using the 0.59-m LONEOS Schmidt telescope. Its cometary apperance was soon confirmed [IAUC 8532, 2005 May 20].
This comet made its closest approach to the Earth on 27 June 2006 (3.177 au), 7 months after its perihelion passage.
Solutions given here are based on data spanning over 2.2 yr in a range of heliocentric distances: 4.06 au – 3.693 au (perihelion) – 6.42 au.
This Oort spike comet suffers slight planetary perturbations during its passage through the planetary system, however these perturbations move out this comet from the solar system.
