Saturns moons

There may be a lot of interesting simulations of the Saturn system .  
Here's one of them :  
Janus and Epimetheus are small moonlets orbiting in near the same orbit around Saturn. At closest they are only separated by about fifty kilometers .  
Do they collide if they approach ? It seems that when they come close to each other ( happens roughly each six years ) they simply change orbits . The one wich was on the inner orbit goes outwards and vice versa.  
Animation hereunder shows the approach in a rotating frame to Janus . Screenshots were made every 20 days .  
The sim was generated with the downloadable simulation "solar system" .

Saturn's moons are the best dynamical playground in the solar system.  On the "simulations" page on the main web site, you'll find a Janus and Epimetheus article.  There's also a few others from the Saturnian system.  In this forum, you'll find a Polydeuces thread.
 
When you have your simulation open, try holding different moons stationary in the rotating frame to expose all the lesser-known resonances too.

You're right ..I wasn't aware of this . The simulation is even called "Janus" . Nice to simulate also is the "Calypso" one .
