Description

Evidence that Comet 67P/Churyumov–Gerasimenko is composed of ancient material preserved from the formation of the early Solar System and that came together under low speed. The evidence collected by Rosetta lies in the comet’s structural properties, the gases detected leaving the nucleus, and observations of surface features.
