This cosmic detective work involved comparing spectrum data on the enigmatic object with data gathered on a known Centaur rocker booster that's been floating around in space since 1971.
The object has attracted a lot of interest due to the mystery surrounding it and the fact that it was captured into an Earth orbit that makes it a cute little visiting mini-moon.The Centaur booster will stick around with us for a few months, but is expected to continue its space adventures back in orbit around the sun sometime in March 2021.
