Logic based planetary definitions...

Since the IAU seems to not want to use a logically based definition for what is and isn't a planet, I'd like to propose something that can actually be applied to any solar system, (or even rogue planets, not in orbit around a star) not just our own.

 

Here's what I have so far.

 

Stellar Object: Star, Black Hole, Binary/Trinary/Qauternary Star, etc.

Primary planetary orbit: Stable orbit around central Stellar Object.

Secondary planetary orbit: Eccentric orbit around central Stellar Object.

Planet: Gravity meeting or exceeding 1.00m/s, exceeding 1000km diameter, sphereoid or oblate sphereoid with less than 10% average deviation. Not a Stellar Object.

Dwarf Planet: Gravity between 0.01m/s and 1.00m/s, exceeding 1000km diameter, sphereoid or oblate sphereoid with less than 10% average deviation. Not a Stellar Object.

Moon: Any object exceeding 0.01m/s gravity in stable orbit around a Planet or Dwarf Planet. Not a Stellar Object. Can still be a Planet or Dwarf Planet.

Binary/Trinary/Quaternary/Etc. Planet: Any Planet or Dwarf Planet with a Moon that causes the system to have a center of mass (barycenter) above the surface any of the Planets/Dwarf Planets.

Don't insult me. I have trained professionals to do that.
