Back when the Earth was crawling with trilobites and other strange shelled creatures, our planet may have had a ring just like Saturn's. This ancient ring system is thought to have formed about 466 million years ago,

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.

The rings of Saturn are some of the most famous and spectacular objects in the Solar System. Earth may once have had something similar. In a paper published last week in Earth & Planetary Science

Once upon a time, Earth may have sported a planetary ring of its very own. The hypothetical ring didn't last long, cosmically speaking – just a few tens of millions of years. But that was long enough to have left a lasting impression on Earth's geological record,

New geological evidence suggests that Earth might once have been encircled by a ring of debris, much like Saturn. This hypothesis, proposed by researchers from Monash University in Australia, was published in the journal Earth & Planetary Science Letters.
