From Larry Harrison:

Re: Protest over new planet definition (Sept. 5): I am in agreement with the new definition of a planet. However, Plutos’ orbit may be closer to the Sun than Neptunes’ for twenty years but it never really crosses it. Does it? If this is the case, then Plutos’ orbit is cleared and it should still be classified as a planet. Also in my opinion, Pluto/Charon is actually a Double Planet. I would like to see all of the differentiated (round) bodies discovered beyond Neptune be given their proper place in the solar system, whether as Planets of Dwarf Planets. I would also like to see this new definition expanded to include Moons. If a Moon isn’t differentiated it shouldn’t be called a moon, just a satellite, natural or captured.
