Its light reflection suggests it is similar to carbon-rich asteroids. While other observatories have yet to confirm its presence, it is not uncommon for Earth to capture such temporary satellites. There is a possibility that the mini moon could be recaptured by the moon's gravity and become a natural lunar satellite, a theoretical class of objects that astronomers believe might exist.
