C / 1999 S4 is a long-period comet that was discovered on September 27, 1999 by the LINEAR project . The comet made its closest approach to Earth on July 22, 2000, at a distance of 0.3724 AU . The diameter of the core of C / 1999 S4 was estimated to be approximately 0.9 km. Before the comet broke up, the rate of core erosion was around 1 cm per day. Around July 5, 2000, the comet became brighter and some fragments became detached from the nucleus. Around July 20th it increased its brightness again and then almost completely dissolved.
