The IAU Minor Planet Center said on the 27th that a dwarf-planet candidate has been identified in the outer solar system. U.S. researchers analysing Vera C. Rubin Observatory data in Chile flagged an icy body provisionally designated 2026ED138; it is estimated at about 46 AU from the Sun, beyond Pluto's ~40 AU, classifying it as a trans‑Neptunian object. If confirmed, it would become the sixth object officially designated a dwarf planet.
