2023 KQ14, informally nicknamed Ammonite, is a trans-Neptunian object (TNO) orbiting the Sun on an extremely wide elliptical orbit. It was discovered by the Subaru Telescope atop Mauna Kea on 16 May 2023, as part of the internationally led astronomical survey "Formation of the Outer Solar System: an Icy Legacy" (FOSSIL). 2023 KQ14 is unusual because the direction of its orbital apsides is not aligned with those of previously known TNOs with high-perihelion elliptical orbits (sometimes known as sednoids), which challenges the hypothesis that an unseen distant planet ("Planet Nine") could be aligning their orbits. 2023 KQ14 likely has a diameter between 220 and 380 km (140 and 240 mi).
