Rubin Observatory finds possible dwarf planet beyond Pluto

The Rubin Observatory in Chile has found a possible dwarf planet beyond Pluto, provisionally named 2026 ED138, the observatory said. It estimated the object is 600 to 1,500 km wide and about 46 times farther from the Sun than Earth. Rubin said it likely went unnoticed because it lies near the Milky Way's plane, a region crowded with stars.
