Description
Comet 67P/Churyumov-Gerasimenko was discovered on Oct. 22, 1969 at Alma-Ata Observatory, Russia. Klim Ivanovic Churyumov found an image of this comet while examining a photographic plate of another comet (32P/Comas Solá) taken by Svetlana Ivanova Gerasimenko on 11 September 1969. It has an irregular, bifurcated (contact-binary) shape with dimensions 4.1 km × 3.3 km × 1.8 km (large lobe) and 2.6 km × 2.3 km × 1.8 km (small lobe), with a rotation period of 12.4 hr. It has an orbit semi-major axis distance of 3.4630 AU with eccentricity of 0.6410. Churyumov–Gerasimenko was the destination of the European Space Agency's Rosetta mission, which rendezvoused with Churyumov–Gerasimenko on 6 August 2014 and entered orbit on 10 September 2014.
