The Brief

  • Astronomers have discovered a possible new dwarf planet in our solar system.
  • The object, named 2026 ED138, may be as large as 1,500 kilometers in diameter.
  • Further observations are needed to confirm its status as a dwarf planet.

Astronomers have identified a potential new dwarf planet in our solar system, located beyond Pluto. The object, designated 2026 ED138, was discovered through ongoing observations.

Scientists believe the celestial body could measure up to 1,500 kilometers in diameter, making it a significant find in the outer solar system. However, its exact size and composition remain under investigation.

Researchers are currently working to determine whether 2026 ED138 meets the criteria for classification as a dwarf planet. This includes assessing its shape, orbit, and whether it has cleared its orbital path of other debris.

The discovery adds to the growing list of objects in the Kuiper Belt and beyond, expanding our understanding of the solar system's structure. Further data will be required to confirm the object's status and its implications for planetary science.
