Astronomers just deleted an asteroid because it turned out to be Elon Musk's Tesla Roadster
The case of mistaken identity was quickly resolved, but scientists say it shows the need for transparency around spaceflight traffic in deep space.
On Jan. 2, the Minor Planet Center at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, announced the discovery of an unusual asteroid, designated 2018 CN41. First identified and submitted by a citizen scientist, the objects orbit was notable: It came less than 150,000 miles (240,000 km) from Earth, closer than the orbit of the Moon. That qualified it as a near-Earth object (NEO) one worth monitoring for its potential to someday slam into Earth.
But less than 17 hours later, the Minor Planet Center (MPC) issued an editorial notice: It was deleting 2018 CN41 from its records because, it turned out, the object was not an asteroid.
It was a car.
To be precise, it was Elon Musks Tesla Roadster mounted to a Falcon Heavy upper stage, which boosted into orbit around the Sun on Feb. 6, 2018. The car which had been owned and driven by Musk was a test payload for the Falcon Heavys first flight. At the time, it received a great deal of notoriety as the first production car to be flung into space, complete with a suited-up mannequin in the drivers seat named Starman.
