143P/Kowal–Mrkos is a periodic comet in the Solar System.
Observational history
Discovery and loss
Antonín Mrkos first reported the discovery of this comet as an asteroid named 1984 JD, after spotting it as a 16th-magnitude object on the night of 2 May 1984.Template:R In September 1984, Charles T. Kowal analyzed photographic plates exposed on the night of 23 April 1984 and he recognized the comet as almost stellar-like, with a faint but discernible coma.Template:R Brian G. Marsden immediately recognized that Kowal's object is identical to that of Mrkos' discovery, allowing him to calculate an elliptical orbit for the object,Template:R which allowed Mrkos to notice that he indeed captured faint cometary activity on images he took on 19 May.Template:R However, it was not observed beyond that date, and was initially considered lost, subsequently redesignated as D/1984 H1.Template:R
Recovery
It was not observed during the comet's predicted apparition in 1992.Template:R Shuichi Nakano later revised his orbital calculations for the comet in 1997, which allowed him to predict that the comet may next return by 2000.Template:R It was successfully recovered on 9 March 2000, when LINEAR and LONEOS spotted an asteroid-like object with a comet-like orbit (Template:Mp), which Marsden noted that it matched those predicted for Kowal–Mrkos.Template:R
