67P is the comet visited by ESA's Rosetta mission, which studied its nucleus and coma in detail and deployed the Philae lander. It is a Jupiter-family periodic comet. 67P/Churyumov–Gerasimenko is approximately 4 km across.
How to observe 67P/Churyumov–Gerasimenko
67P/Churyumov–Gerasimenko changes in brightness and position around perihelion. Confirm a current ephemeris before observing because catalogue orbital values alone are not a live forecast.
