Planet Rings Could Be Behind the Formation of Solar System Satellites
ScienceDaily (Dec. 4, 2012) — Two French researchers have recently proposed the first ever model explaining how the great majority of regular satellites in our solar system were formed out of planet rings. The model, the only one of its kind, was first tested in 2010 on Saturn's moons. It seems to account for the present distribution of "giant" planets and also explains how the satellites of the "terrestrial" planets such as Earth or Pluto came into being. These results are a major step forward in understanding and explaining the formation of planet systems across the universe.
