Scientists have discovered that a small Kuiper Belt Object, named 2002 XV93, appears to possess a thin atmosphere, a phenomenon that defies current scientific understanding. This object, significantly smaller than Pluto, should not have enough gravity or warmth to retain gases. The discovery was made possible by observing a stellar occultation event in January 2024, which revealed a gradual dimming of starlight, indicating the presence of a gaseous layer. Researchers are exploring theories such as recent geological activity or a past impact event to explain how this atmosphere might be sustained. AI
