Distances are in AU (Astronomical Units). 1 AU is the average distance between the Earth
and the Sun. (n+4)/10 is the formula proposed by Titius/Bode. The row labelled
d shows the actual distances in AU, as measured by astronomers. Notice that the
value predicted for Neptune actually seems to fit Pluto, while the value predicted for
Pluto does not seem to correspond to any known object. 1992QB
