24. 1. Earth's Ancient Ring System Approximately 466 million years ago, during the Ordovician Period, Earth may have possessed a ring system similar to Saturn's. This hypothesis suggests that a large asteroid breached Earth's Roche limit, disintegrating into debris that formed rings around the equator. These rings could have contributed to a global cooling event by blocking sunlight, leading to significant climatic shifts. Earth Science Questions
