I believe the criteria used to determine whether a celestial body is a planet is overly complex and should be simplified. We're pulling human factors into determination. Size, mass, SHAPE, and composition should NOT be factored into the determination. Alien worlds must be given alien consideration - not a dogmatic narrow view based on human experiences.
Simply put, a planet should have two things:
1. A planet should maintains an orbit within a system. Otherwise it can be classified as an asteriod or comet.
2. A planet can be a statellite to zero or more stars. It cannot be a satellite to another planet.
What is your opinion? What criteria should be used to determine a planet?
