A weird number of craters are located close to the equator, and the odds that this is random are incredibly low, researchers say.

Earth may have had a giant ring of space rocks surrounding it, similar to those around Saturn, which could have led to chaotic meteorite strikes on our planet's surface, new research suggests. The hypothesized ring may have formed roughly 466 million years ago and was the remains of a gigantic asteroid tugged apart by Earth's tidal forces after passing our planet's Roche limit.

A ring of asteroid debris could have orbited Earth for tens of millions of years, and perhaps even have altered the planet's climate

Scientists have presented evidence that Earth may have had a ring. The existence of such a ring, forming around 466 million years ago and persisting for a few tens of millions of years, could explain several puzzles in our planet’s past.
