There is no evidence that "planets become more frequent at lower

Consider the evidence of your senses.  I assume you've seen planets, but
if not, I'll tell you *my* experience.  Of the six planets and five moons
I've seen with my own eyes (sometimes aided by binoculars), Joseph's
observation holds true.

Careful searches reveal an ever-increasing number of objects in our solar
system at ever-smaller sizes.  Extrasolar observations hint that our
system is not atypical.
