I would have guessed that they looked at the ages of the planets moons to constrain planet formation age. Unidentified capture could push the earliest estimate, but with many moons maybe it works anyway.But I can see how this may be more accurate, and timely considering the current mission.[Damn! Another interesting observation to wait years for. The length of the astronomical pipeline is so aggravating for outsiders... yes, yes, it's a big universe. Sigh!] Aha.

These are not mutually exclusive categories.
