Why does Saturn have a ring system?

Probably the reason for the formation of the rings is several consecutive absorptions by Saturn of its satellites.

Calculations show that after Saturn was formed, several large satellites orbited close to Saturn. Gradually, due to gravitational effects, these satellites one after another "fell" into the bowels of Saturn.

In the process of descending from their orbits and entering the spiral trajectory, the satellites were destroyed. At the same time, the light ice component remained in space, while the heavy mineral components of the celestial bodies were attracted by the planet.

As a result, one of them was swallowed by the hole and the other two were thrown into intergalactic space by a powerful gravitational kick. The two soon merged into one massive star.
