          The Earth-like orbit of the object and its orbital evolution suggest that
    it could be of an artificial origin, launched from the Earth decades ago or a 
    lunar ejecta. Even though the nature of the object remains uncertain, the object 
    is being designated in hope that this can facilitate its further follow-up.
