Comet 67P/Churyumov-Gerasimenko – Surprise! Contact binary.

Rosetta_67PCG_14July_2014

So Rosetta is landing on this comet soon. As it got closer there was talk that the comet may be two-fee, two comets orbiting a barycenter. That is probably what it was at one point in time, however now it is a contact binary. These two nuclei began fusing somewhat recently into what now looks like a rotating rubber ducky without a beak. Go, go, go!
