Re: Confused
That's no excuse for having an ambiguous and sloppy definition just so one has a small list of planets for kids to learn.
How would you extend that definition on exo-planets? Say, in a solar system so young that none of its planets has yet cleared its orbit?
I'm fine with calling Pluto, Charon, Ceres, Juno, Pallas etc. planets. You can then further divide 'planets' into 'major' (our standard eight) and 'minor' (everything else).
