We might be able to start using this as a way to specify planets, rather than the arbitrary number-by-discovery. Try StarName(with catalog info)#log(approximate radius of orbit)

Earth would we Sol#0 Kepler-90#-1.3, Kepler-90#-1.1, out to Kepler-90#0 for the outermost one on his graph.

That way, finding a new planet doesn't require either renumbering to specify where the planet is relative to the star. (BTW, I'm not real happy about using AU as the base measurement. It might be better to use Megameters since you're less likely to end up with negative log)

What would you do for highly elliptical orbits?
