Research suggests Earth might have once boasted a spectacular ring similar to Saturn's, formed from an asteroid breakup around 466 million years ago. This event coincides with numerous meteorite impacts primarily around the equator and a subsequent period of significant global cooling.

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.

Earth and Saturn might be a lot more similar than previously thought. In a new study, a team of researchers suggests that 466 million years ago, a ring system made up of asteroid remnants may have surrounded our planet,
