New sednoid “Ammonite” discovery deepens Planet Nine mystery Astronomers have found 2023 KQ14, nicknamed Ammonite, a rare sednoid with a unique orbit that challenges the Planet Nine hypothesis.

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

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 ...

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

For reference, Pluto’s average distance from the Sun is about 40 AU, so 2023 KQ14 is quite distant. At 23.4 billion miles (37 ...

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

Researchers just got a step closer to understanding the origins of our solar system, with the discovery of an object orbiting ...

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 ...

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

The “new world” was found as part of the survey project FOSSIL (Formation of the Outer Solar System: An Icy Legacy), hence its nickname, Ammonite. An ammonite is a fossil of a cephalopod that died out ...

The new sednoid, called 2012 VP113, was discovered by Chadwick A. Trujillo and Scott Sheppard of the Gemini Observatory in Hawaii. Its closest approach to the sun is 7.4 billion miles, which is 80 ...

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.
