Lost comets can be compared to lost asteroids (lost minor planets), although calculation of comet orbits differs because of nongravitational forces, such as emission of jets of gas from the nucleus. Some astronomers have specialized in this area, such as Brian G. Marsden , who successfully predicted the 1992 return of the once-lost periodic ...

This is a list of comets (bodies that travel in elliptical, parabolic, and sometimes hyperbolic orbits and display a tail behind them) listed by type. Comets are sorted into four categories: periodic comets (e.g. Halley's Comet), non-periodic comets (e.g. Comet Hale–Bopp), comets with no meaningful orbit (the Great Comet of 1106), and lost comets (), displayed as either P (periodic), C (non ...
83D/Russell (previously 83P/Russell) is a periodic lost comet in the Solar System with an orbital period of about 7.5 years. On the post-1988 orbit the comet probably does not get brighter than about apparent magnitude 21. The comet might come to perihelion in late May 2021, but the uncertainty in the comet's position is a few million km.
