According to NASA, which regularly tracks cosmetic activity, a giant asteroid will pass by Earth on Tuesday, January 28. Asteroid 2025 BS4 is approximately 22 feet in diameter and 17 to 40 feet across.

New research suggests that Earth's recent mini-moon might have originated as part of our actual moon long, long ago.

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.

The “asteroid” wasn’t a space rock after all. It was a cherry-red Tesla Roadster that Elon Musk launched into space to much fanfare in 2018 as part of a publicity stunt during the maiden flight of SpaceX’s Falcon Heavy rocket. The car, complete with a mannequin named “Starman” in the driver’s seat, had been orbiting the Sun ever since.

The case of mistaken identity was quickly resolved, but astronomers say it shows the need for transparency around craft in deep space.
