- 1999_F1 abstract "C/1999 F1 (Catalina) is a long-period comet discovered on March 23, 1999, by the Catalina Sky Survey.The comet has an observation arc of 2,360 days allowing a good estimate of the orbit. The orbit of a long-period comet is properly obtained when the osculating orbit is computed at an epoch after leaving the planetary region and is calculated with respect to the center of mass of the solar system. C/1999 F1 will make its closest approach to Neptune in 2017. Using JPL Horizons, the barycentric orbital elements for epoch 2035-Jan-01 generate a semi-major axis of 33,300 AU, an apoapsis distance of 66,600 AU, and a period of approximately 6 million years. Comet West has a similar period.".
