When Earth Had Rings

In our solar system, Saturn’s rings are the brightest and most extensive, but other planets like Jupiter, Uranus, and Neptune also have their own. Surprisingly, four icy minor planets orbiting among or beyond gas giants also host ring systems. A new study suggests that Earth may have had a ring system around 466 million years ago, with evidence of increased large impacts and changes in climate. Researchers propose that the Earth captured a system of rings from an asteroid, explaining the concentration of impacts at the equator during the Ordovician period. This theory opens up a new way of thinking about Earth’s history and the potential for multiple ring phases on other planets.
