C/2000 U5 (LINEAR) is a single-apparition comet discovered on October 29, 2000, by Lincoln Near-Earth Asteroid Research.[1] The comet has an observation arc of 362 days[2] allowing a good estimate of the orbit. C/2000 U5 is, as of 2015, the 13th most hyperbolic comet ever discovered and will leave the Solar System.
Before entering the inner Solar System for a 2000 perihelion passage, C/2000 U5 had a barycentric (epoch 1960-Jan-01) orbit with an apoapsis distance of 5,473 AU, and a period of approximately 143,000 years.[3]
The comet came to perihelion on March 13, 2000.[2] As the comet was leaving the inner Solar System, it passed within 0.766 AU of Jupiter on February 3, 2001,[4] Since an epoch of 2000-Dec-06, C/2000 U5 has had a barycentric eccentricity greater than 1,[3] keeping it on a hyperbolic trajectory that will eject it from the Solar System. In 2029, when it is more than 50 AU from the Sun and beyond the influence of the planets, it will still have a barycentric eccentricity of 1.0057.[3]
Comet C/1980 E1 has an even greater eccentricity.
