Evidence Suggests Earth Had a Saturn-like Ring System 466 Million Years Ago

Scientists have found evidence indicating that around 466 million years ago, Earth might have had a ring system akin to Saturn's, formed by a massive asteroid impact. This catastrophic event likely created a debris ring around the equator, as shown by the concentration of 21 impact craters in equatorial regions during the Ordovician period. The existence of this ring could have significantly influenced the global climate by casting shadows that caused prolonged cooling, possibly triggering the Hirnantian Ice Age, the coldest period in the last 500 million years of Earth's history
