The existence of this object was first hypothesized to explain a periodicity described by David Raup and Jack Sepkoski, though the universality of that periodicity was challenged by a recent Paul Renne and Timothy Culler study on moon rocks.

If it is a Brown Dwarf as suggested by Whitmere and Jackon, then the WISE mission will be able to detect it. Calculations that place this object in the constellation Hydra are supported by Lynn Yarris, as well as by the primary proponent of this object's existence, Richard Mueller. This object may cause mass extinctions on Earth by disrupting the Oort Cloud and causing an influx of comets into the inner solar system. For ten points, name this hypothesized red or brown dwarf, which some heterodox astronomers believe to be in a binary system with the Sun.
