In the frenzy of discussion recently over just what a "Planet" is, I figured why not come up with my own definition?
After all, I am completely unqualified, have no right to do so whatsover, and probably wouldn't care in the end what effect it would have.
So here we go:
The Definition of a Planet:
(1) A body in orbit around a sun, and not in orbit around any other body that is in orbit around a sun, except in the case where the body is in orbit around a sun that is in turn in orbit around another sun.
(2) Has sufficient mass to achieve hydrostatic equilibrium and have a nearly spherical shape.
(3) A body that has diameter of 1,275.6 KM (1/10th the Earth's diameter) or greater.
(4) If said body meets criterion (1) and (2) but not (3) the following applies:
(a) If the body is below 1,275.6 KM in diameter it is to be designated a 'Dwarf Planet'.
(b) If the body is above 38,268 KM (3 times Earth diameter) the body is designated a 'Giant Planet.'
There. Problem solved. Astronomers can go back to their scopes now.
***Note - Under this definition, Pluto and a whole host of other bodies in the solar system would become 'dwarf planets', while the rest of the true planets in the solar system retain the appropriate designations.
