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,

C ould Earth once have had a planetary ring like the ones around Saturn? Scientists from Monash University in Australia think so. In a recent paper they identify 450m-year-old craters that lie close to Earth’s historical equator.

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.

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.

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