Researchers working with the Vera C. Rubin Observatory in Chile report a large object beyond Neptune, named 2026 ED138, that appears to be a candidate dwarf planet. The New York Times reports the object is probably a new dwarf planet. The object sits in the Kuiper Belt, a region of icy and rocky bodies past Neptune. According to the New York Post, the team traced it through 30 detections over 20 nights of observations between March and July 2026, and its orbit lies within Pluto’s distance range from the Sun. The Washington Times reports that it would be the sixth confirmed dwarf planet in the solar system if it is confirmed.
