C/2000 Y1 Tubbiolo
more info
C/2000 Y1 was discovered on 16 December 2000 by A.F. Tubbiolo with the 0.9m Spacewatch telescope at Kitt Peak. At once, pre-discovery detections by LINEAR going back to 24 October 2000 were found [IAUC 7544, 2000 December 18].
This comet made its closest approach to the Earth on 23 November 2000 (7.000 au), 2.3 months before perihelion.
Solution given here is based on data spanning over 2.0 yr in a range of heliocentric distances: 8.00 au – 7.975 au (perihelion) – 8.86 au.
This Oort spike comet suffers tiny planetary perturbations during its passage through the planetary system; however, they could lead to escape of the comet from the solar system on hiperbolic orbit (see future barycentric orbit).
