C/2000 H1 LINEAR
more info
Comet C/2000 H1 was discovered three months after perihelion passage and next observed up to one year in a range of heliocentric distances from 3.72 au to 5.35 au. However, the observations are unevenly distributed in this period – there is a ten-month gap between 28 June 2000 and 24 April 2001.
Comet had its closest approach to the Earth on 19 May 2000 (3.385 au).
This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system that lead to a more tight future orbit (see future barycentric orbit).
