First dwarf planet candidate in our solar system is identified

In the outer reaches of our solar system, beyond the orbit of Pluto, NSF–DOE Vera C. Rubin Observatory has spotted 2026 ED138 — a large, bright trans-Neptunian object that scientists have identified as a dwarf planet candidate.

The observations were announced by the International Astronomical Union Minor Planet Center (MPC). If confirmed, ED138 would be among the largest dwarf planets ever discovered in this region of the solar system.
