Sednoid

A sednoid is a trans-Neptunian object with a large semi-major axis, a distant perihelion and a highly eccentric orbit, similar to that of the dwarf planet Sedna. The consensus among astronomers is that there are only four objects that are generally agreed to belong to this population: Sedna, 2012 VP113 ("Biden"), 541132 Leleākūhonua, and 2023 KQ14…
