Astronomers have discovered a possible new dwarf planet orbiting far beyond Pluto. First detected in March 2023 by Japan's Subaru Telescope in Hawaii, this object has been dubbed 2023 KQ14 and ...

Astronomers have found 2023 KQ14, nicknamed Ammonite, a rare sednoid with a unique orbit that challenges the Planet Nine hypothesis.

Japan's Subaru Telescope in Hawaii detected a faint, icy body. Now named 2023 KQ14, or Ammonite, it lies well beyond Pluto.

The celestial body's unusual orbit “implies that something extraordinary occurred" in the early days of the solar system—and ...

Typically, telescopes are synonymous with bringing far-off objects close, but the newest member of the solar system was ...

"It is possible that a planet once existed in the solar system but was later ejected, causing the unusual orbits we see today ...

The discovery was made by astronomers using the Subaru Telescope, which is situated atop a dormant volcano in Hawaii.

A tiny object far beyond Pluto, newly discovered by the Subaru Telescope, could reshape our understanding of the early Solar System. Named 2023 KQ14, this rare “sednoid” follows an unusual orbit that ...

After discovering the first sednoid, Sedna, researchers believed they would find more quickly, but that didn’t happen — V113 and Sedna are the only two that have been discovered so far.

The sednoid is estimated to be between 136 and 236 miles (220 and 380 kilometers) wide. That makes it 45 times wider than the height of Mount Everest.
