"Wrong, most people in the US have NOT accepted the IAU definition, at least the part that says dwarf planets are not planets at all. It is the IAU
that is imposing its eight-planet propaganda on the whole world and asking everyone to blindly accept a flawed definition adopted by only four percent
of its members, most of whom are not planetary scientists, in a process that violated its own bylaws. In fact, hundreds of professional astronomers
led by Dr. Alan Stern, Principal Investigator of NASA's New Horizons mission to Pluto, immediately responded with a formal petition rejecting the IAU
McDonald's representatives have admitted they know about the controversy. What the Register refuses to recognize is that they chose NOT to accept the
IAU definition. Interestingly, it's the supporters of Pluto's planet status who publicly admit the matter is still up for debate. The IAU and Mike
Brown have done everything possible to suppress all debate, claiming the issue is settled when it clearly is not.
There is nothing wrong with the solar system being crowded with planets. It's hard to imagine any scientific justification for artificially narrowing
the number of planets just because having "too many" is inconvenient for some people.
According to Stern and like-minded scientists, a planet is a non-self-luminous spherical body orbiting a star. The spherical part is important because
it means an object is in large enough to be shaped by its own gravity, a state known as hydrostatic equilibrium and characteristic of planets, not of
shapeless asteroids. This definition gives our solar system 13 planets: Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto,
Haumea, Makemake, and Eris.
In short, there IS still a very real debate over the status of Pluto.

I don't know much about this debate and I don't know if this counts as crossposting, but it's from the OP's own link's comments, so I don't see
why it would be unacceptable to mention. But of course, if it is, I'd gladly remove it so please don't take away what few remaining ATS points I
Anyway I think she brings up alot of great points, and it shows that not everyone is in agreement about what a planet is or isn.t Some think there are
8 planets and some think 13? Seems we need to do alot more work about planets here on our own planet before we try and actually travel to any of
In fact, we need to clean house so to speak and clean up our planet, but that's neither here nor there.
But I will always have a soft spot in my heart for Pluto, since it was discovered so recently by an American in 1930 I believe if my memory serves.
And ever since I was in school, I was always taught it was a planet. He's the little underdog of our solar system, all cold and frigid and lonely,
but still struggling to hang in there and not become detatched and drift aimlessly into the black abyssal maw of oblivion.
