For nearly 200 years astronomers have repeatedly claimed evidence for new planets beyond Neptune. All such claims have eventually been shown to be wrong. Until now? Eight years ago Konstantin Batygin and I showed new evidence that a giant planet is influencing the orbits of bodies in the distant Solar System. Since that time, the evidence has gotten progressively better, but the planet still has not been found. I’ll discuss the evidence for this new planet – Planet Nine – and talk about how we are trying to uncover this first new planet in our solar system in nearly 200 years.
