The Rubin Observatory Finds Its First Dwarf Planet Candidate
The Vera Rubin Observatory found a distant Solar System object before its decade-long Legacy Survey of Space and Time even got started. The object is a dwarf planet candidate named 2026 ED138, and if confirmed, it will be one of the largest dwarf planets beyond Neptune. It may be up to 1500 km in diameter.
