The Spin Orbit Resonance Between Saturn and Neptune
New scenario could explain not just Saturn's stunning rings, but also its axial tilt and the somewhat elongated orbit of the planet's largest moon, Titan. The authors say Saturn escaped the spin orbit resonance with Neptune, whose at once had an additional moon orbiting between the orbits of Titan and Lapidus. When Titan drifted outwards, this moon, which is named Chrysalis, became trapped in the 3-1 resonance with Titan,. However, computer simulations showed that this resonance wouldn't have lasted; it would have become chaotic. And if Chrysalis was indeed ripped apart, then Saturn's impressive ring system may be part of its icy remains.
