Is there evidence of an approaching Planet X or Nibiru?

I encounter persistent online claims about a hidden planet (Nibiru/Planet X) destined to disrupt Earth's orbit. As an astronomy student, I want to address these claims authoritatively. What would be the unambiguous observational signatures of such a massive, nearby object, and why do professional sky surveys like Pan-STARRS or WISE rule out its existence as described in doomsday scenarios?

From the perspective of observational astronomy, there is zero credible evidence for such an object. I have worked with data from infrared all-sky surveys like NASA's WISE mission, which would have easily detected a Jupiter-sized or larger planet within the solar system, let alone one approaching Earth. Its gravitational influence would also be glaringly obvious in the orbits of the outer planets we track these with extreme precision. The claims rely on fabricated images and a misunderstanding of celestial mechanics. While astronomers do search for possible distant "Planet Nine" based on subtle Kuiper Belt clustering, this is a hypothetical, slow-moving object in a distant orbit, not an incoming doomsday body. The two concepts are completely different.
