A Tennessee family recently discovered that their doorstop was, really, out of this world.
Scientists confirmed that the 33-pound, oval rock is actually a 4-billion-year-old meteorite that likely fell to Earth during a meteorite strike in 1853, the Lexington Herald-Leader reported.
Donna Lewis told Fox News her grandfather picked the meteorite out of a cow pasture in Kentucky in the 1930s.
It's served as a door stop through the years and was even painted green and used as decoration in a flower bed at one time.
Lewis and her husband, George, took the rock in for testing after running a metal detector over it in May. To George Lewis' surprise, the detector's dial registered "overload," according to the Herald-Leader.
After confirming its meteorite status, Eastern Kentucky University purchased the rock for eventual display.
"To have something in your possession that's that old, it's just unreal," Donna Lewis told the Herald-Leader.
