Requirements

 * A planet is a celestial body in orbit around a star or stellar remnants
 * Has sufficient mass for self-gravity and is nearly spherical in shape.
 * A planet must not share its orbital region with other bodies of significant size (except for its own satellites)
 * Must be below the threshold for thermonuclear fusion of deuterium.
 * If a celestial body meets those requirements, it is considered a planet; at that point, the planet is further classified by its atmosphere and surface conditions into one of twenty Eight categories.
