Could Earth Have Had Rings Like Saturn? Study Suggests Asteroid Breakup and Cooling Climate

https://ift.tt/jWedqG6 Scientists have proposed that Earth may once have had a ring system similar to Saturn’s, formed by an asteroid breakup 466 million years ago. This ring may have triggered global cooling, contributing to the Hirnantian Ice Age. Evidence includes impact craters near the equator and meteorite debris in sedimentary rocks.
