83D/Russell
Sign in to saveAlso known as Russell 1, 1979d Russell, 1979 V Russell, 1985b, 1985 IX
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.

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.
== Discovery == The comet was discovered on a photographic plate on 16 June 1979 by Kenneth S. Russell at the UK Schmidt Telescope, Australia, who described it as faint and diffuse, with a very low brightness of magnitude 18. Calculations of its orbit suggested a perihelion date of 27 May 1979 and an orbital frequency of 6.13 years.
