Damocloids are believed to originate from this body, which is located outside the oligarch halo. Gliese 710 is predicted to move through the outer edges of this body. The depletion problem of this body is solved by the interaction via galactic tides between the spheroidal outer region and the proposed dense inner toroidal region. The scattered (*) disc has been proposed as the primary source of objects in this body. John Matese proposed the existence of a gas giant in this body nicknamed Tyche, while another hypothetical object in this body thought to cause periodic mass extinctions is called Nemesis. 2008 KV2 and 90377 Sedna are possible candidates of its inner region. Archetypal objects like McNaught, Hale-Bopp, and Halley are thought to originate here. For 10 points, name this region of the solar system thought to be the origin of long-period comets.
