The ring would have gradually fallen to Earth as meteorites, correlating to a spike of impacts seen in the geological record.

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,

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.

Evidence suggests Earth had a ring system 466 million years ago, causing a surge in meteorite impacts and possibly influencing the planet's climate.
