C/2001 B1 LINEAR
more info
Comet C/2001 B1 was discovered on 22 January 2001 with Lincoln Laboratory Near-Earth Asteroid Research project, that is 4 months after its perihelion passage. It was observed until 8 January 2002.
Comet had its closest approach to the Earth on 5 December 2000 (2.544 au), 2.5 months after its perihelion passage and 1.5 month before discovery.
Solution given here is based on data spanning over 0.961 yr in a range of heliocentric distances from 3.18 au to 5.34 au.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system; however, these perturbations lead to escape the comet from the planetary zone on a hyperbolic orbit (see future barycentric orbits).
