The ring would have gradually fallen to Earth as meteorites, correlating to a spike of impacts seen in the geological record.

Research suggests Earth might have once boasted a spectacular ring similar to Saturn's, formed from an asteroid breakup around 466 million years ago. This event coincides with numerous meteorite impacts primarily around the equator and a subsequent period of significant global cooling.

Researchers have found evidence suggesting that Earth may have had a ring system, which formed around 466 million years ago.
