00:00Our solar system may have a new dwarf planet, hiding far beyond Pluto.
00:04It's called 2026 ED-138, spotted in images from the new Rubin Observatory in Chile.
00:11The object is about 46 times farther from the Sun than Earth.
00:14That's over 4.2 billion miles away.
00:17Scientists estimate it's roughly 370 to 930 miles across.
00:22For comparison, Pluto is about 751 miles wide.
00:26Its exact size is uncertain because its reflectivity isn't known yet.
00:30Infrared observations should help confirm what it is.
00:33There are five recognized dwarf planets today, including Pluto, Ceres, and Eris.
00:39ED-138 could become the sixth and potentially the largest.
00:43It likely hid for years against a crowded stretch of the Milky Way.
00:47Rubin's camera is the world's largest at 3,200 megapixels.
00:51In early testing, the observatory found more than 11,000 new asteroids.
00:56And its 10-year sky survey has only just begun.
