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

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.
