In 2016, Konstantin Batygin and Mike Brown shook up the field of planetary science when they proposed an additional planet in the outer Solar Sytsem: "Planet Nine". Since that time, Konstantin, Mike and many others have been working hard to flesh out and verify the hypothesis. Konstantin swung by the Cool Worlds Lab this week to tell us about his most recent work on Planet Nine and the latest from observational search efforts.
