Jerry,

Iridium was originally envisaged as an array of 77 communication satellites - 77 being the atomic number of Iridium. Think of earth as the nucleus, the satellites as the electrons, in the standard high school model of the atom.

In fact it's actually around 66 satellites, but "Terbium" doesn't have quite the same cachet. More at the Wiki here:

Larry, Kevin and List, why are these reflections called "iridium flares"? Is the surface reflecting the sunlight an iridium alloy?
