They found that the P9-inclusive simulations more accurately reflected what astronomers see in the Solar System, which means that some planetary body (possibly around 400 to 800 time further from the Sun than Earth) has avoided our gaze for millennia.

An Astronomer Has Found the Hardest Evidence Yet for the Elusive Planet Nine

We could be getting closer to solving the universe’s biggest mystery

Over the course of millennia, scientists have made some pretty big strides in figuring out how our Solar System ticks. Putting the Sun in the center was a big help (thanks Copernicus), and discovering distant planets such as Uranus and Neptune—while discounting other phantom planets such as Vulcan—helped describe some of our system’s strange orbital anomalies.

But while there’s certainly been progress, the work is far from over—especially because wobbles in the orbits of our far flung ice giants (along with dwarf planets like Pluto and Sedna) suggest there’s something out there that we’re still missing.

A fair number of explanations have been put forth to try and understand this unexplained “wobble,” including undiscovered belts, a grapefruit-sized primordial black hole, or even (more controversially) a misunderstanding of astrophysics. However, the leading theory is that far beyond the orbit of Neptune lies another planet that is causing these orbital perturbations—Planet Nine.
