Orbital Dynamics Suggests A Recent Formation of Saturn's Moons - Matija ...

The
age of Saturn's rings and the source of Enceladus's hydrothermal energy
have been hotly debated topics for years. Recently the age of Saturn's
moons interior to Titan, previously thought to be as old as Saturn, also
became actively debated. I will show how computer simulations of the
past orbital dynamics of Saturn's moons Tethys, Dione and Rhea can tell
us how long they have been around. It appears that the inner moons and
rings of Saturn are only about 100 million years, equivalent to the
Cretaceous period on Earth. I will also discuss how the present moons
likely originated from debris resulting from a major orbital instability
in which the previous generation of icy moons was destroyed.
