When is an asteroid not an asteroid? When it's Elon Musk's Tesla Roadster, it turns out.
The wannabe asteroid, announced on Jan. 2 as 2018 CN41, is actually a Tesla Roadster launched into space years ago by SpaceX CEO Elon Musk. The company sent the car (with a spacesuit-clad mannequin called "Starman" in the driver's seat) into a long orbit around the sun in 2018 as the first payload of the company's Falcon Heavy rocket.
