      If you don't say how big an asteroid is, saying a meteoroid is smaller than one isn't much help.

      You know its an asteroid if you can land an experimental shuttle on it and dispatch a oil rig team to blow it up. Otherwise it's a meteoroid.

      A comet has a coma? A comet IN a coma? A comma? A typo? I'm confused! (I DO love that narwhal)

      A comet sometimes has a coma, usually when it's close to the sun. A coma is cloud of ice and dust particles.

      There's no good definition of a meteoroid, but most places suggest they're pieces of rock and dust in space less than a meter (around a yard, or three feet) in diameter. JPL has more on the differences.

      I'm absolutely shocked that there's some nonspecific guidelines for nomenclature on NASA's website somewhere. Usually everything is incredibly cut / dry /clear.

      Maybe I remain bitter because of poor, forsaken Pluto.

      Hmm. I hope I used that word right..."nomenclature"
      it's very very late, and my vocabulary disappears after 1am. :)

      I'm not surprised that there isn't a cut and dry definition; my guess is that the IAU hasn't adopted one yet.
