The Moons Prove The Point
Round worlds have interesting things going on that differentiate them from inert lumps of rock or the periodic phase changes associate dwith comets. I feel that the large moons deserve a category that elevates them to the equals of planets in terms of complexity and worthiness of study. I feel that they should have long ago been levated to the level where school children are taught their names. Shortening the list of planets is a simple excuse for avoiding discussing the diversity of interesting worlds in the solar system. I'm far more interested in Ganymede, Europa, Io, Titan, Triton, and Enceladus than Mercury. Instead of just memorizing a list of planets childeren should be learning about the worlds in the solar system.
