A theorized inner region to this area is named after Hills.  Safranov and Cameron proposed the two most widely accepted models of its origin, and the object Gliese 710 may cause havoc here sometime within the next ten million years.  2000 CR105 is one of only two objects identified that may belong to this group.  Richard A. Muller suggested that a brown dwarf that orbits the sun periodically disrupts this area, and it extends nearly a quarter of the way to Proxima Centauri.  For 10 points, name this region of space thought to contain 90377 Sedn
