Computer simulations conducted by an international team of researchers with the participation of the University of Bern showed that the two-piece comet 67P/Churyumov-Gerasimenko, short ‘Chury’, may have formed through a violent collision of two larger bodies. These collisions took place not only during the formation, but also in later evolutionary stages of our solar system. Therefore, ‘Chury’ could be younger than previously assumed. The simulations demonstrated that a large fraction of the post-collision material aggregates in many small bodies, some of them taking the shape of long two-piece bodies, similar to that of ‘Chury’. The highlight of the comet’s investigations by the European spacecraft Rosetta was the release of the lander Philae in November 2014 before the mission ended in September 2016 with a targeted crash of Rosetta into the comet.
