67P/Churyumov–Gerasimenko
67P/Churyumov-Gerasimenko (abbreviated as 67P or 67P/C-G) is a Jupiter-family comet,[1] at first from the Kuiper belt,[2] with a current orbital period of 6.45 years, a rotation period of about 12.4 hours[3] and a maximum speed of 135,000 km/h (38 km/s; 84,000 mph).[4] Churyumov-Gerasimenko is about 4.3 by 4.1 km at its longest and widest dimensions.[5] It was first followed on photographic plates in 1969 by Soviet astronomers Klim Ivanovych Churyumov and Svetlana Ivanovna Gerasimenko, after whom it is named.[6]
It latestly came to perihelion (closest approach to the Sun) on 2 November 2021,[7][8][9] and will next come to perihelion on 9 April 2028.[10]
