NASA has confirmed a remarkable celestial discovery: Earth now has a second moon. This small quasi-moon will accompany our planet and its primary Moon on their orbital journey until the year 2083.
A team of astronomers from the University of Hawaii made the discovery of this new object, which has been officially designated 2025 PN7. It was first detected in the summer of 2025.
Scientists estimate the quasi-moon’s size to be between 18 and 36 meters wide, making it roughly the dimensions of a small building.
