And what is the next distance out that fits in [Bode's] law? Is there
anything at that (what is the term?) orbital distance?

After 38.8 (Pluto) would come 77.2. The Oort cloud is expected to be
out in light year territory, or around 50000 AU, extending to even
twice that, so it has no cozy relationship to 77 AU.

The object provisionally designated 2003 UB313, but nicknamed "Xena"
while it awaits an official name and number, averages about 68 AU. 90377
Sedna's perihelion is about 76 AU, but its mean distance from the Sun is
more like 500 AU. They also have highly inclined orbits. These minor
planets, well beyond the Kuiper Belt, are classified as "Scattered-Disk
Objects".

I take it, then, that you agree that these objects have some
relationship to the paragraph of mine that you clipped:

"The Kuiper Belt is a belt - at 30 to 50 AU, it is far wider than the
narrow zone that Bode's law would imply (which would be at ~40 AU,
Pluto's neighborhood). Also, objects well beyond the 50 AU distance are
known."
