View Full Version : How old are the moons of Saturn?

In 2016, astronomers came to the conclusion that they could only be a hundred million years old, based on tidal effects (https://theconversation.com/saturns-moons-may-be-younger-than-the-dinosaurs-so-could-life-really-exist-there-56860)

But crater counts suggest they are billions of years old (http://gcp.fcaglp.unlp.edu.ar/_media/integrantes:mzanardi:surface_ages.pdf)

and here there is evidence that Enceladus could have had a molten core for billions of years (https://www.scientificamerican.com/article/a-porous-core-may-heat-the-ocean-of-enceladus/)

So how do I reconcile this?

In the first article it states that there could of been a previous generation of moons so the core of Enceladus might of existed before present day Enceladus. Plus this is just a model and needs more evidence to support it.
