C/2006 E1 McNaught
more info
C/2006 E1 was discovered on 11 March 2006 by Robert H. McNaught on the Siding Spring Survey images taken with the 0.5-m Uppsala Schmidt telescope [IAUC 8688, 2006 March 16]. After perihelion passage in January 2007, it was ocassionally observed starting from 26 January 2008 until 3 March 2009 (see figure).
This comet made its closest approach to the Earth on 3 July 2006 (5.382 au), six months before perihelion.
Solution given here is based on data spanning over 3.0 yr in a range of heliocentric distances: 6.39 au – 6.041 au (perihelion) – 8.07 au.
This Oort spike comet suffers small 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).
