Experts say that compared to the sun's equator, our Sun is tilted by about 6 degrees. Since the 1970s, astronomers have not been able to figure out why this is happening. Now, experts think they may have found a solution: Planet Nine. Elizabeth Bailey works at the California Institute of Technology in Pasadena as an astrophysicist and planetary scientist.
She says that planet nine tilted our sun by six degrees and that the missing planet may have also tilted the other planets over the course of the solar system's history. Planet Nine is a celestial body that hasn't been found yet but is thought to be at the very edge of our solar system. Konstantin Batygin and Mike Brown predicted its existence in January 2016.
