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.

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.

Musk launched his personal Tesla Roadster into space on February 6, 2018, as a test payload for the Falcon Heavy rocket.

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