C/2003 G1 LINEAR
more info
C/2003 G1 was discovered on 8 April 2003 by the LINEAR as an apparently asteroidal object. In the next two days its cometary apperance was reported by many observers [IAUC 8115, 2003 April 10]. At the moment of discovery it was about 2 months after its perihelion passage.
This comet made its closest approach to the Earth on 31 May 2003 (4.103 au), almost four months after perihelion.
Solution given here is based on data spanning over 1.5 yr in a range of heliocentric distances from 4.94 au to 6.77 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).
