Silly question - is Pluto "a planet" or not ???
perhaps a very silly question...
a while ago, there was a move to downgrade the status of Pluto - from "planet" to "minor body" I was told today that it was now "definitive", and astronomers no longer call it a planet so, what *is* the current statue of Pluto ??? |

Silly question - is Pluto "a planet" or not ???
There is no clear physical definition of "planet" (as distinct from
"asteroid"). So the question is, in a sense, meaningless. It's like trying to distinguish between a river and a creek. Pluto is either an abnormally small planet or an abnormally large asteroid! None of the physical properties of Pluto are in dispute. wrote in message ... perhaps a very silly question... a while ago, there was a move to downgrade the status of Pluto - from "planet" to "minor body" I was told today that it was now "definitive", and astronomers no longer call it a planet so, what *is* the current statue of Pluto ??? |

Your query coincides with a question on this topic broadcast on the "QI" program, so I guess that's where your information came from. The "correct" answers to questions on QI seem to often be quite different from what is normally accepted as reality. QI isn't a quiz in the conventional sense, the questions are there mainly to provoke "interesting" discussions, and points are awarded for interestingness rather than correctness. Similarly the "correct" answers seem often to be chosen for being interesting rather than for being correct. In QI, the contestants are penalized for providing boring answers. The boring answer to "How many planets are there in the solar system?" was "nine" and the interesting answer was "eight". Similarly the boring answer to "How many moons does the Earth have?" was "one" and the interesting answer was "two". -- Mike Williams Gentleman of Leisure |

Silly question - is Pluto "a planet" or not ???
I was going to mention QI, but some people say there are 10 planets in the
solar system (depends if you count Quaror - I think thats it, if spelt wrong). Also, does anyone know about that moon, cuithney or something? Larry "Mike Williams" wrote in message ...

It has some interesting resonances with Earth so that every so often it approaches closely and then gradually moves some way around the orbit, a long way from Earth. It cannot collide with the Earth, but is co-orbital rather than being in orbit around the Earth. So the answer to the QI question should have started with "Could you please define exactly what you mean by moon?" There are also a few asteroids in orbits between Earth and Mars. -- Mike Dworetsky (Remove "pants" spamblock to send e-mail) |
