Over 80 researchers from more than a dozen institutions recently worked together to study such an "artificial meteor" -- NASA's OSIRIS-REx sample return capsule -- as it reentered Earth's atmosphere.

Reports of artificial objects in space pose issue. Because of the Tesla Roadster’s fame, it's included in a database maintained by NASA’s Jet Propulsion Lab called Horizons, according to Astronomy ...

The center said on its website that 2018 CN41’s registry was deleted after "it was pointed out the orbit matches an artificial object, 2018-017A, Falcon Heavy Upper stage with the Tesla Roadster.

This asteroid might not hit Earth in 2032 after all—here’s how we know. Space agencies have systems in place to spot, track, and forecast the future orbits of potentially hazardous asteroids.
