Rosetta’s comet 67P is much younger than previously thought

14 November 2016 Astronomy Now

Based on computer simulations, astrophysicists at the University of Bern conclude that comet 67P/Churyumov–Gerasimenko did not obtain its duck-like form during the formation of our solar system 4.5 billion years ago. Although it does contain primordial material, they are able to show that the comet in its present form is hardly more than a billion years old.

Astronomers predict possible birthplace of Rosetta-probed comet 67P

Canadian researchers have charted a path that most likely pinpoints the very origins of 67P/Churyumov-Gerasimenko, the comet studied intensively by ESA’s Rosetta spacecraft. Western University astronomers believe that 67P is made from primordial material and relatively new to the inner parts of our solar system, having only arrived about 10,000 years ago.
