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

And now, a new study published in the scientific journal Earth and Planetary Science Letters seems to show that Earth itself once had a similar ring. The new study asserts that Earth's ring formed around 466 million years ago and stuck around for around 40 million years before dissipating.
