Penn State researchers say the moon was captured during a close encounter between Earth and a terrestrial binary.

They say Earth 's gravity separated the binary, snagging one of the objects, making it a satellite.

The moon's initial elliptical orbit contracted over a timescale of thousands of years .

At its current distance from Earth , the moon now feels a significant tug from the sun.
