How big does a planet have to be to be a planet?
To be considered a planet, an object must be massive enough to be rounded into a spheroid by its own mass but not massive enough to cause thermonuclear fusion. Additionally, a planet must be orbiting a star or what used to be a star, and it must not be part of a disk of similar objects, like a Kuiper belt object.

What are the rules for a planet not to be considered a planet?
Pluto is not a planet because it has not cleared everything from its orbit. The rules of a planet are:It orbits the SunIt is large enough for gravity to squash it into a ballIt must have cleared everything in its orbit (Pluto did not fulfill this).
Characteristics of planets?
The IAU came up in 2006 with three definitions for a planet: # It must orbit the Sun. # It must be large enough for gravity to mould it into a nearly spherical shape. # It must have cleared the neighbourhood around its orbit. The third definition excluded Pluto as a planet.

It must empty its area of orbiting debris. (This one is often contested) If something fulfills the first two qualifications it is considered in the least a dwarf planet.

In order to be a true planet, a planet must meet these three criteria.It must be an object which independently orbits the SunIt must have enough mass so that gravity pulls it into a roughly speroidal shapeIt must be large enough to "dominate" its orbit (ie. its mass must be much larger than anything else which crosses its orbitPluto does not meet all 3 criteria, therefore it is not a true planet, but a Dwarf Planet.
