Preferred term

Epimetheus  

Definition(s)

  • Epimetheus is an inner moon of Saturn. It was discovered in 1980 from photos taken by Voyager 1 and is also known as Saturn XI. Epimetheus is located between Saturn's F- and G-rings and shares the same orbit as Janus. Normally separated by about 50 km, every 4 years these two satellites approach each other, exchange a small amount of momentum, and swap places. It is possible that they formed from the break-up of a single parent object. (Encyclopedia of Science, by David Darling, https://www.daviddarling.info/encyclopedia/E/Epimetheus.html)
