Though the mini-moon will only be in Earth’s orbit for about two months, it’ll stay close to the planet for a few months, making its closest approach in January 2025, after which it’s expected to make a return to the planet’s orbit in 2055, according to the study.
Earth had planetary rings like Saturn 466 million years ago
Earth May Have Had a Ring Like Saturn Once
“Over millions of years, material from this ring gradually fell to Earth, creating the spike in meteorite impacts observed in the geological record,” said Tomkins in a statement that accompanied the paper’s release. “We … see that layers in sedimentary rocks from this period contain extraordinary amounts of meteorite debris.”
