It turns out I invented a new way of estimating average distances between planets.

From a Physics Today article by Tom Stockman, Gabriel Monroe, and Samuel Cordner, published on March 12, 2019:

As best we can tell, no one has come up with a concept like PCM [point-circle method] to compare orbits. With the right assumptions, PCM could possibly be used to get a quick estimate of the average distance between any set of orbiting bodies. Perhaps it can be useful for quickly estimating satellite communication relays, for which signal strength falls off with the square of distance. In any case, at least we know now that Venus is not our closest neighbor—and that Mercury is everybody’s.

It's hard to believe that three professional researchers somehow missed out From the Narrow Desert in their literature review, but I'm claiming priority on this. I independently used the same method in my post "The geocentric order of the planets," published November 9, 2018. At the time I had no idea that I was doing anything other than slapping together a kludge to avoid having to do any math above my pay grade, but apparently I was making an Original Contribution to Physics.

Thanks to reader Kevin McCall for bringing the Physics Today article to my attention.
