Scientists suggest Earth once had rings like Saturn, formed from broken asteroid chunks. These rings likely fell to Earth, causing meteor strikes near the equator around 466 million years ago. The study indicates these impacts contributed to a global cooling event known as the Hirnantian Icehouse.

Earth may once have had Saturn-like ring, scientists say
Earth may briefly have had a ring system similar to Saturn’s over 450 million years ago during a period of unusually intense meteorite bombardment, a new study proposes. Scientists assessed 21 asteroid craters from the “Ordovician impact spike” period 466 million years ago and noticed that these were strangely located in a narrow band of land close to the equator,
