Impact craters found around the Earth that were made around the same time could be linked to debris falling from a ring, a new study suggests.

Researchers have found evidence suggesting that the Earth may have once had a system of Saturn-like rings. The rings are theorized to have formed 466 million years ago during one of the coldest periods in the planet's history, known as the Ordovician.

Researchers have found evidence suggesting that our planet may have once had a ring system around 466 million years ago.

In a discovery that challenges our understanding of Earth's ancient history, researchers have found evidence suggesting that Earth may have had a ring system that formed around 466 million years ago,

A new study from Monash University scientists suggests that Earth may have had a ring system that formed around 466 million years ago, during the middle Ordovician, from ca. 466 Ma. The findings challenge our understanding of Earth’s ancient history.

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.

The gas giants in the outer solar system are the homes to ring systems today, but almost half a billion years ago, our planet may have had a temporary ring, too.
