Orbit's of three known Sednoids

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 three known Sednoids:

• 90377 Sedna
• 541132 Leleākūhonua
• and 2012 VP113.

These sednoids have very eliptical orbits and it could be Planet 9's gravity changing their orbits, or these object's were captured by the Sun.
