A model of the geometry of Comet 67P / Churyumov–Gerasimenko nucleus.
Sometimes nicknamed "the rubber ducky" due to the shape of its bi-lobal structure, 67P / Churyumov–Gerasimenko, was visited by the Rosetta spacecraft and its lander Philae in 2014, after a 10 year journey.
1:200000 model is about 22.5mm across
1:100000 model is about 45mm across
1:75000 model is about 67mm across
1:25000 model is about 90mm across
The model is based on the latest navcam shape model by ESA, which can also be found here
