Journey to Dwarf Planet Candidate 2026 ED138 | Vera C. Rubin Observatory

Journey to Dwarf Planet Candidate 2026 ED138 | Vera C. Rubin Observatory

This video shows the location of newly discovered dwarf planet candidate 2026 ED138 (ED138). It was discovered in observational data from the National Science Foundation (NSF)–U.S. Department of Energy (DOE) Vera C. Rubin Observatory spanning March 4–July 11, 2026.

ED138 was found by Rubin Operations team member and in-Kind contributor Matthew Holman (Center for Astrophysics | Harvard & Smithsonian). He contributes to improving Rubin's algorithms that search for distant moving objects in our Solar System. Its distance from the Sun places it beyond the orbit of Pluto, and initial analysis indicates that it may be among the largest and brightest bodies scientists have discovered in this region of the Solar System.

Rubin Observatory is jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science.
