Neptune always sits there as a big fat gassy giant spoiler. mathematical coincidence with a degree of fudge rather than an actual law.
BT right. certainly not a universal law. not observed in any of the exo planet systems so far.
Neptune's position exactly between Uranus and Pluto at 9,6 AU for the establishing of a lower 3 and upper 96 limit to the geometric progression of the Bode sequence.
( the innermost and outermost planets are equisistant).
Bode / Titius is a 9 place coincidence, ? is the universe old enough to allow for that? lucky us,
. because stability is made from resonances like that.
Think of the planet spacings as wavelengths, the ecliptic as a Chladni plate.
7 octaves like on a piano.
