Observational Constraints on Planet Nine: Cassini Range Observations
Abstract
We significantly constrain the sky position, distance, and mass of a possible additional, distant planet in the solar system by examining its influence on the distance between Earth and the Cassini Spacecraft. Our preferred region is approximately centered on (RA, Dec) = (40, -15), extending approximately 20 degrees in all directions.
