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

In a surprising twist on our planet’s ancient history, scientists are now suggesting that Earth might once have had a ring system, similar to the rings we see around Saturn today. A new study presents compelling evidence that this ring formed around 466 million years ago,

New geological evidence suggests that Earth might once have been encircled by a ring of debris, much like Saturn. This hypothesis, proposed by researchers from Monash University in Australia, was published in the journal Earth & Planetary Science Letters.
