The new study asserts that Earth's ring formed around 466 million years ago, and stuck around for around 40 million years before dissipating. Researchers say that the existence of such a ring would help solve several puzzles from Earth's past and that much of the data they collected supports its existence.

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.

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.

From Grace Earth may have had its own ring system that formed around 466 million years ago, lasting for tens of millions of years. As detailed in a new study published in the journal Earth and Planetary Science Letters,

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.
