- 1999_S4 abstract "C/1999 S4 (LINEAR) is a long-period comet discovered on September 27, 1999, by LINEAR.The comet made its closest approach to the Earth on July 22, 2000, at a distance of 0.3724 AU (55,710,000 km; 34,620,000 mi). It came to perihelion on July 26, 2000, at a distance of 0.765 AU from the Sun.The comet nucleus was estimated to be about 0.9 km in diameter. Before the comet broke up, the (dust and water) nucleus erosion rate was about 1 cm per day. The comet brightened near July 5, 2000, and underwent a minor fragmentation event.The comet brightened again around July 20, 2000, and then disintegrated. The published optical and most radio data support that the main nuclear decay started July 23, 2000. The dust cloud expanded at about 20 meters per second (45 miles per hour) while the fragments expanded at around 7 m/s (16 mph). Other comets are known to have disappeared, but Comet LINEAR is the first one to have been caught in the act.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. Using JPL Horizons, the barycentric orbital elements for epoch 2010-Jan-01 generate a semi-major axis of 700 AU, an aphelion distance of 1400 AU, and a period of approximately 18,700 years.".
