C/2003 T3 Tabur
more info
Comet C/2003 T3 was discovered on 14 October 2003 by Vello Tabur (Australian Capital Territory); that is 6.5 months before its perihelion passage. It was observed until 3 May 2005.
Comet had its closest approach to the Earth on 22 May 2004 (2.319 au), about 3 weeks after its perihelion passage.
Preferred solution given here is based on data spanning over 1.55 yr in a range of heliocentric distances: 2.968 au – 1.481 au (perihelion) – 4.63 au, however NG solution based on pre-perihelion data (pn) is also adequate for past calculations.
This Oort spike comet 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 1,400 au.
