Planetary Classification Proposal
(C)2009 Ignoring the IAU's politically motivated and unscientific classification of planets (which only applies to our solar system), I've decided to make my own proposal.
I invite anyone to try to shoot holes in my proposal.
My proposal - (seriously, freely distribute this but at least give me credit if you use it) - actually gives our solar system a maximum of 10 PRIME planets, although we would come out with several "Secondary" "rogue" and "non-solar" planets.
The first step to determining planetary status is determining 'what a planet is not' rather than 'what a planet is'.
A planet is NOT:
1. Free roaming or otherwise lightly bound mass of particles/matter (nebula)
2. An active comet (as defined by the visual of icy tail, orbit, and a-symmetrical composite surface)
3. A star (a ball of gaseous particles undergoing nuclear fusion to create heat and energy)
4. An Asteroid (as defined by the a-symmetrical, rock conglomeration devoid of a core).
5. Unbound or otherwise irregular matter
6. Spacial Anomaly
7. *Open Ended Definition to be updated should other formations of stellar origin be discovered or defined.
A planet can be:
1. A satellite of any other stellar body (including a moon. This would allow for the definition: Secondary Planet, Primary Planet).
2. An unbound tightly bound mass which may or may not be symmetrical, providing it has a defined Core, through either gravitational pull or solid material (allowing for the definition of Rogue Planet)
3. A planet beyond the scope required to be heated by the nearest stellar body, or a planet orbiting a dead stellar body (allowing for the definition of Cold Planet)
Definitions unbefitting a planet
Dwarf/Giant Planets – Considering the fact that size is arbitrary, this definition is purely unscientific
Proto Planets – It may be a fact discovered later on that what we consider to be a developing planet has completed its development stage and provided life
Plutons – By the very logic of the Pluton classification, are we to call Earth (one of the smallest planet types in the universe) an Earthton?
Definitions befitting a Planet
Orbital Primary Categories
Orbital (i.e. a planet with a clear planar orbit, despite the orbital shape)
Rogue (a planet which despite personal movement, is not bound to any singular object such as an orbital or cluster planet)
Complete Rogue (a planet which isn't linked to a galaxy (let alone a solar system)
Cluster (a planet which despite personal movement or uniformity, is more of member of a group, i.e. clearly bound to multiple celestial entities, but this binding isn't as planar as an Orbital planet).
Orbital Locality Categories
Primary (a planet which orbits a solar entity within a radius in such that it directly affects the gravity/orbit of more than one other Solar Object or the Sun itself, or is in-between the lineup of other such planets fitting this description. i.e. this would be a main System Planet)
Non-Solar (a planet which falls outside of the solar definition, in that it does not directly affect one or more Solar Objects, and is not followed by a planet fitting the Primary description)
Secondary (a planet which orbits another planet - this would actually qualify Io as a planet. Current debates on Titan as well)
Stable Orbit (a planet with a stable orbit is one which repeats its orbit with predictability, regardless of the shape or length of orbit)
Instable Orbit (a planet which orbit changes erratically or otherwise routinely alters its path outside of a simple repetitive predictability. A planet which does a figure 8 would be stable, but a planet which does all sorts of shifts in speed and direction is instable)
Stable Rotation (a planet with a consistent smooth rotational speed and axis, regardless of whether or not it speeds up or slows down over an extended period of time, or flips axis)
Instable Rotation (a planet whose rotation and axis will speed up, slow down, and change position without cause, in an irrational, instable manner that causes internal damage or otherwise severe and drastic changes in conditions which cannot be compensated by the planets natural structure).
Orbital Sub Categories
Complimentary (A planet smaller in size which essentially affects only one other solar planet in a helpful, non destructive fashion, yet is incapable of being classified as a Primary Planet – i.e. the lesser of two masses locked into geosynchronous rotation or orbit)
Contrary (a planet which has a direct negative/conflicting effect on another planetary object)
Living Planet (a planet which is active in one of the following ways: core, rotation, shifting plates. This definition has no link to actual living organisms or orbital nature)
Dead Planet (a planet which is completely inactive in means of core, plates, rotation, etc... This definition has no link to actual living organisms or orbital nature)
Dormant (a dead planet which can through minimal means be brought from a seemingly dead status, or near dead status, to a fully active status. This definition has no link to actual living organisms or orbital nature)
