Astronomers have discovered a dwarf planet candidate, dubbed ED138, which takes approximately 280 years to orbit the sun, appearing in telescope images from the Vera C. Rubin Observatory in Chile. To confirm its classification as a dwarf planet, researchers need to determine its size, with initial observations suggesting it may be relatively large. The discovery was made by Matthew Holman, a senior astrophysicist at the Smithsonian Astrophysical Observatory, and his colleague Kevin Napier, who were sifting through data and spotted the object among over 2,000 newly discovered small objects in the distant solar system, sparking cautious excitement about the potential for a new dwarf planet in our solar system.
