How do YOU define a planet?

Question

I'm still irked about last August's "demotion" of Pluto.
I define a planet as:

1) Large enough to make it spherical.
2) Has cleared it's calculable path (orbit) of smaller objects.
3) Orbits it's star (sun) and no other object (if it orbits another planet than it's a moon).

Answer 1

i think this planet is messed up by how many wars anf small conflits we are having. we are also poullting the enviroment,why we do,because were lazy and technology has taken over.

Answer 2

By the new definition a planet
* is in orbit around the Sun,
* has sufficient mass so that it assumes a hydrostatic equilibrium (nearly round) shape, and
* has "cleared the neighborhood" around its orbit.

A non-satellite body fulfilling only the first two of these criteria is classified as a "dwarf planet", whilst a non-satellite body fulfilling only the first criterion is termed a "small solar system body" (SSSB). The definition was a controversial one, and has drawn both support and criticism from different astronomers.

by the new standards, pluto is a dwarf planet. And we added Eris and Ceres as fellow dwarf planets.

Answer 3

I don't define planet some big dude sitting some place in a space in time has defined it, I don't get into planets that much. I just know that there is a man in the moon and he has cheese, no that was men that went to the moon, right, LOL I am sorry that this bothers you.

Answer 4

Well, I tend to agree with you but will for the time being go with the International Astronomical Union. Pluto doesn't know about its demotion and continues to merrily go around the sun in its highly inclined orbit.

Answer 5

a big bunch of rocks

Answer 6

I'll go three.
