Earth will soon part ways with a “mini moon,” asteroid 2024 PT5, which has been tagging along for the past two months.

On Monday, the asteroid will be pulled away by the sun’s gravity, but it will return for a brief visit in January.

NASA plans to observe the 33-foot asteroid with radar to learn more about it, as it may be a chunk of rock ejected from the moon.

While not technically a moon, it has been following a horseshoe-shaped path around Earth, the Associated Press has reported.

After its January visit, the asteroid will zoom away into the solar system, returning in 2055.
