Three Moons

Last time two moons, Mimas and Enceladus; this time three: Mimas again (the big one), with Epimietheus apparently next to it and Daphnis underneath Mimas, right in the ring plane and perturbing the Keeler Gap. I said Epimetheus was "apparently" next to Mimas - in reality the whole of the rings lies between them. Mimas is between Cassini and the rings, and Epimetheus is on the other side. In reality, Mimas is only just over three times as large as Epimetheus.
