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,

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.

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

Earth and Saturn might be a lot more similar than previously thought. In a new study, a team of researchers suggests that 466 million years ago, a ring system made up of asteroid remnants may have surrounded our planet,

A ring could explain a mysterious arrangement of impact craters near the equator and might even have caused an ice age, according to a new study
