C/2000 W1 Utsunomiya-Jones
more info
Comet C/2000 W1 was discovered on 18 November 2000 by Syogo Utsunomiya (Aso, Kumamoto, Japan), Albert F. Jones (Nelson, New Zealand); that is a bit more than one month before its perihelion passage. It was observed until 23 January 2001.
Comet had its closest approach to the Earth on 25 November 2000 (0.280 au), one week after its discovery.
Solutions given here are based on data spanning over 0.159 yr in a range of heliocentric distances: 0.858 au – 0.321 au (perihelion) – 0.820 au..
This comet (original semimajor axis of about 8,000 au) suffers large planetary perturbations during its passage through the planetary system; these perturbations lead to a significantly more tight future orbit with semimajor axis of about 600 au.
