GoKawiilVera C. Rubin Observatory spots possible sixth dwarf planet beyond Pluto
Astronomers using the Vera C. Rubin Observatory in Chile have identified a distant icy object, provisionally named 2026 ED138, orbiting about 46 astronomical units from the Sun. Based on its brightness and estimated reflectivity, researchers believe it measures between 600 and 1,500 km across, potentially making it the largest trans-Neptunian object found in two decades. The object was detected by Harvard astrophysicist Matthew Holman using a search code, then confirmed across 30 images spanning 20 nights, with older data tracing its path back to 2016.
