Astronomers spot a possible new dwarf planet 46 times farther out than Earth

Dwarf planet candidate appears which takes roughly 280 years to orbit our sun

Sifting through Vera C. Rubin Observatory data, Matthew Holman and colleagues found 2026 ED138, an object 46 times farther from the sun than Earth that takes 281 years to orbit. Traced back to 1937 photographic plates, it may be 370 to 930 miles wide — big enough to be round, and possibly the sixth dwarf planet. Infrared or stellar-occultation observations are needed to confirm its size.
