Pluto is still a planet

Contrary to the ranting of some so-called "scientists", Pluto is still a planet.

Scientific"opinion" is always subject to change and frequently does.

My reasoning is:

  1. There is no valid reasoning for a minimum size per se.
  2. There is no valid reasoning for physical composition per se.
  3. Sufficient mass to give the body a spherical shape due to gravity is a sound argument.
  4. Orbiting around the Sun rather than primarily around another planet/body is a sound argument.
  5. I can accept that scientists might tentatively revoke Pluto's status as a planet, but that tenative status revocation should remain tentative for at least five if not ten years to permit subsequent reasoning and actual scientific experiments to validate the revocation. Mistakes can be made, and only the passage of time is sufficient protection against grevious error. Spur of the moment Passion should never be a basis for scientific judgment.

As far as the asteroid goes, I would say that the jury should remain out until we have sufficiently clear measurements and images to clearly see the shape of the body. I saw the picture, but it was way too fuzzy to say that it is definitive. It certainly looked round, but we all know how deceiving looks can be. I see no valid arguments per se against a planet existing within the asteroid belt.
