The new paper titled "The population of natural Earth satellites," from Cornell University's Mikael Granvik, Jeremie Vaubaillon and Robert Jedicke states that these "secret moons" enter and exit the Earth's orbit without notice.
"At any given time, there should be at least one natural Earth satellite of 1-meter diameter orbiting the Earth," Granvik writes.
Scientists have confirmed at least one such temporary moon, discovered by the Catalina Sky Survey in Arizona in 2006.
"Our results are consistent with the single known natural [temporarily-captured orbiter] 2006 RH120, a few-meter diameter object that was captured for about a year starting in June 2006," the report says.
