Some observations have lead scientists to believe that there may be a ninth planet in our solar system, 10 times the mass of the earth. The two main reasons are…
1) Six of the most distant known Kuiper belt objects (celestial objects found in the Kuiper belt; a region in the outer Solar System, extending from the orbit of Neptune at 30 AU to approximately 50 AU from the Sun) have orbits that can only be explained if a massive object’s gravity was pulling on them.
2) Initially, it was predicted that Planet Nine's gravity would cause another set of Kuiper belt objects to have orbits perpendicular to Planet Nine's orbit.🪐 Since then, five objects have that fit this description have been discovered.
Nonetheless, some astronomers question this hypothesis, and assert that the strange orbits is due to observing biases, resulting from the difficulty of discovering and tracking these objects during much of the year.
