A Sednoid in astronomy is a small object like a small solar system body, that goes around the Sun beyond Neptune's orbit, similar to the orbit of the dwarf planet Sedna. There are only four known Sednoids:
- 90377 Sedna
- 541132 Leleākūhonua
- 2012 VP113 ("Biden")
- 2023 KQ14 ("Ammonite")
These sednoids have very eliptical orbits and it could be Planet 9's gravity changing their orbits, or it could be that these objects were captured by the Sun from another star.
