New Telescope Detects Hidden World Beyond Pluto that Could Rank Among Largest Ever Found

A powerful new telescope has discovered a dwarf planet candidate beyond Pluto — and scientists say it could be among the largest of its kind ever found in the reaches of our solar system.

The discovery, announced Oct. 27, was made using observations from the Vera C. Rubin Observatory, a newly operational facility located on a mountaintop in Chile.

The observatory, jointly funded by the U.S. National Science Foundation and the Department of Energy’s Office of Science, began its 10-year survey of the sky in June 2026, using the world’s largest digital camera to search for previously unseen objects.

Researchers identified the object as 2026 ED138. They estimated it measures between 370 and 930 miles across.

“If confirmed, ED138 would be among the largest dwarf planets ever discovered in this region of the Solar System,” the observatory said in a statement. (Read more from “New Telescope Detects Hidden World Beyond Pluto that Could Rank Among Largest Ever Found” HERE)
