Canup and Ward have a new, interesting paper ("A common mass scaling for satellite systems of gaseous planets") in the June 15, 2006, issue of Nature. See the Editor's Summary for more details.

The mass ratios of Titan to Hyperion, Tethys to it's co-orbitals, Dione to its co-orbitals, possibly Mimas to the Herschel impactor, and possibly Callisto to the Valhalla impactor are all around (IIRC) 5000 to 1.
Weird, huh? |

Weird, huh? There's probably some reason for it, with orbital mechanics associated with all sorts of factors 'boiling off' everything other than a strictly limited range of masses relative to their 'primaries'. You'd end up selecting for some mass ratio or other... Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!
