The 3D figure shows the orbits of the distant, extreme Trans-Neptunian Objects (TNOs), here defined as objects with semi-major axes greater than 250 AU and perihelion distances greater than 30 AU. The orbit of the newly-discovered extreme TNO, 2015 BP519, is plotted in red. This figure uses X3DOM and should work on recent versions of Chrome, Firefox, and Safari.
