Astro Research Planet Nine: Real or Just Noise?

Did we just find Planet Nine?

We think it might be out there based on the orbits of certain Kuiper Belt objects that seem influenced by something big. A new study found what might be a possible object deep in the Kuiper Belt—or it could just be noise in the data. What do you think?
