C/2006 K1 McNaught
more info
C/2006 K1 was discovered on 17 May 2006 by Robert H. McNaught on the Siding Spring Survey images taken with the 0.5-m Uppsala Schmidt telescope [IAUC 8712, 2006 May 18].
This comet made its closest approach to the Earth on 30 October 2007 (3.761 au), 3.3 months after perihelion.
Solution given here is based on data spanning over 2.8 yr (3 oppositions) in a range of heliocentric distances: 5.60 au – 4.426 au (perihelion) – 6.41 au.
This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system that lead to escape of the comet from the solar system on hiperbolic orbit (see future barycentric orbit).
