C/2002 R3 LONEOS
more info
C/2002 R3 was discovered on 4 September 2002 by the LONEOS as an apparently asteroidal object. A few days later its cometary apperance was reported by observers [IAUC 7970, 2002 September 14].
This comet made its closest approach to the Earth on 13 September 2003 (3.004 au), three months after perihelion.
Solution given here is based on data spanning over 1.7 yr in a range of heliocentric distances: 4.57 au – 3.869 au (perihelion) – 4.88 au.
This Oort spike comet suffers slight planetary perturbations during its passage through the planetary system; however, they can lead to escape of the comet from the solar system on hiperbolic orbit (see future barycentric orbit).
