Scientists have discovered a sednoid, named Ammonite, beyond Neptune. This icy object challenges existing theories about the outer solar system's formation.

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 ...

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 2023 KQ14, nicknamed "Ammonite", was discovered using the Subaru Telescope and is a highly elliptical object with a perihelion and aphelion that places it beyond the heliopause, ...

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.
