The small near-Earth asteroid 2024 PT5 has been creating a buzz among researchers. Discovered last year with the help of a NASA-funded telescope, it is only about 33 feet across and does not pose any threat to Earth.

For a brief, but exciting, time last year, Earth had two moons. A small asteroid lingered close to our planet in its orbit around the Sun, temporarily caught by Earth’s gravity to become a far away mini-moon. A closer look at the space rock reveals a rather familiar origin: Earth’s mini-moon might actually be a broken-off piece of our regular Moon.

Earth's temporary asteroid friend last year was a chunk of its real moon that had been blasted into space thousands of years ago, scientists find.

Last year, astronomers on the hunt for potentially dangerous near-Earth asteroids spotted something unusual. A space rock, now dubbed 2024 PT5 made several close passes by Earth, not quite orbiting our planet,
