Title: Planet Nine from Outer Space
The recent suggestion of evidence for a massive ninth planet in the outer solar system has set off a worldwide search to find this latest member of our planetary family. I will discuss the evidence for the planet and show how we are working to constrain the mass and orbital parameters of the body. I will also point out some of the unexpected features in the solar system that this ninth planet explains, including obliquity of our sun. Finally I will show the latest results from the search for Planet Nine.
