When I saw this development–the target of the space probe Rosetta is a double comet–I wondered if this will make landing the probe more difficult. Then I thought about this celestial body, Comet 67P/Churyumov–Gerasimenko. Will one lobe get named Churyumov and the other Gerasimenko?
Svetlana Ivanova Gerasimenko took the photograph, above. Klim Ivanovych Churyumov found the comet on the 1969 picture.
