Not having seen this answered, a quick check of the Voyager Web site,
<URL: http://voyager.jpl.nasa.gov/ > (and the weekly mission reports)
finds that Voyager 1 is at 98 AU and Voyager 2 is at 79 AU.
The Kuiper Belt, and most TNOs, orbit at distances of about 30 to 50
AU. Indeed, there seems to be a significant edge to the Kuiper Belt
around 50 AU.
Sedna (2003 VB12) has a perihelion distance of about 75 AU, and I
believe that it is approaching perihelion within the next several
decades, so it's close to this distance now.

V1 98
V2 79
Kuiper Belt 30--50
Sedna > 75
