Its motion appeared smooth and delicate, maintaining a steady trajectory without visible propulsion or debris. Based on apparent speed, brightness, and parallax against the lunar surface, the object could be consistent with a near-Earth object, space debris reflecting sunlight, or a plasma-related atmospheric phenomenon occurring at orbital distance. The ab
