NSF�DOE Vera C. Rubin Observatory has found a large object that scientists have identified as a possible dwarf planet. A preliminary data analysis shows that the object is orbiting in the outer reaches of the solar system beyond Pluto and may be one of the largest dwarf planet candidates ever found. If confirmed, the object would join the five other known dwarf planets: Pluto, Ceres, Eris, Haumea, and Makemake. , , , , Rubin Observatory is jointly funded by the U.S. National Science...

Podría tratarse de un mundo nuevo dentro de nuestro sistema solar . Un planeta enano hasta ahora desconocido, atisbado por primera vez gracias al Observatorio Vera C. Rubin en las gélidas y oscuras profundidades del espacio, mucho más allá de la órbita de Plutón. Se llama 2026 ED138 y, si se confirman las primeras estimaciones, podría estar entre los cuerpos más grandes descubiertos hasta ahora en esa remota frontera. Los astrónomos han estimado que su diámetro oscila entre 600 y 1.500...
