Scientists have proposed a fascinating new idea: Earth may have once possessed a ring system, akin to that of Saturn. These rings could have formed around 466 million years ago, during a tumultuous era marked by intense meteorite bombardment known as the Ordovician impact spike.

Evidence suggests Earth had a ring system 466 million years ago, causing a surge in meteorite impacts and possibly influencing the planet's climate.

If astronomers had been walking the Earth 466 million years ago, they may have had something special to see. The moon and the planets and the stars and the sun would have looked pretty much the same as they do today.
