The Vera C. Rubin Observatory has discovered a new Dwarf Planet candidate in our solar system - 2026 ED138, a large, bright trans-Neptunian object orbiting beyond Pluto.
Distance from Sun: ~46 au (1 au is the average distance between the Earth and the Sun. Pluto has an average distance of 40 au)
Orbital tilt: 25°
Diameter: 600 - 1500 km
If confirmed, ED138 would be among the largest dwarf planets ever discovered in this region of the Solar System.
