Earth may have had rings. At least that's what a new study published this month claims. Here's what we know so far.

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,

To reach that surprisingly conclusion, scientists studied the positions of 21 asteroid impact craters during the Ordovician period – the second of six periods in the

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.

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.

During a tumultuous period for our planet around 466 million years ago, Earth was pelted with meteorites and rocked by tsunamis. But geologists have uncovered some strange things about this moment in history.

Earth may have once possessed a ring system, akin to that of Saturn. These rings could have formed around 466 million years ago, during a tumultuous era marked by intense meteorite bombardment known as the Ordovician impact spike.
