One of the main attractions of the 'COMETS - The Rosetta mission: A Journey to the origins of the Solar System' exhibition at the Museum für Naturkunde in Berlin was a faithful four-metre 1:1000 scale model of Comet 67P/Churyumov-Gerasimenko. It was built on the basis of a digital terrain model of 67P that scientists from the DLR Institute for Planetary Research in Berlin-Adlershof generated using stereoscopic data from the German camera on board the Rosetta mission.
