Map of the trans-neptunian region, October 1997. The circles indicate the orbits of the giant planets. The Kuiper Belt objects are shown in their current location with their designations (e.g., QB1, TG2, and so on). Note that on the scale of this map, the inner part of the Oort Cloud would be about 3 meters away from the figure. Map courtesy of Gareth V. Williams, Harvard-Smithsonian Astrophysical Observatory.
