A planet can quickly be defined:  As a body which orbits a [[star]]; is in [[hydrostatic]] [[equilibrium]] under it's own mass; and dominates the region of space in which it moves (i.e. the [[gravity]] and rotation of the object have caused it to assume a roughly spherical shape and the region of it's orbit is generally free from other forms of astronomical matter)<ref>http://www.iau.org/iau0603.414.0.html</ref>.
