Earth had Saturn-like rings 466 million years ago, new study suggests

  1. I assume Earth must have caught and tore apart a second small moon we had or an asteroid.  After all this is too modern for it to be debris from the moon’s formation 

  2. No really accurate to call them “Saturn-like” rings. It may have been a ring, but the defining feature that would make a ring system “Saturn-like” would be if it was composed entirely or at least nearly of water ice. Which in Saturn’s case was almost certainly formed by plumes of vapor coming from its many water moons. Which obviously Earth never had.
