Abstract We discuss an updated dynamical and statistical analysis of cometary evidence suggesting that the Sun may have a Jovian mass companion orbiting in the outer regions of the Oort comet cloud. Such a companion could also have produced the detached Kuiper Belt object Sedna. If the object exists, evidence for it likely resides in the data collected by the recently completed Wide-field Infrared Survey Explorer (WISE) mission.
