Kepler’s third law is not wrong, but a mistake
In astronomy, Kepler’s laws give a description of the motion of planets around the Sun. Kepler's laws are only valid when not affected by the gravity of other planets, however，Kepler’s third law does not follow this restriction. For this reason, It simply has no use at all in our Solar System. Kepler's third law assumes that all planets are not affected by the gravity of other planets and the orbit of every planet is an ellipse with the Sun at one of the two foci.This is not true. If the planet did not affected by the gravity of other planets, then the orbit of every planet is a circle. The orbit of the planet have an ellipse only because affected by the gravity of other planets. Kepler’s third law, T2/a3=K, only good for comets and not for our Solar System, for this mistake we have a new third law as T2/√(ab)3=K.

Fourth law:
In solar system, All planets, no matter their size, their mass, their shape, their radius should follow (ab)3/2 / T2/=1,

Where T is Orbit Period,

a is the semi-major respect to earth

b is the semi-minor respect to earth

Fifth law:
In solar system, every precession of the orbits of planets has different ellipses. Every different ellipse has its orbital eccentricity between maximum e and 0. And all different ellipses have the same area, include circle of e=0.

For example:
The precession of the orbit of Mercury is 11.83 degree/ century. Every year have different ellipse between e= 0.20563069 and e=0, but every different precession with different ellipse or circle has the same area.

Sixth law:
To determine whether it is a planet or not, it is not according their size, their mass, their radius, or their shape, but one must fulfill the forth law.

Conclusion:
1. Obviously, Pluto does not follow the fourth law, therefore, Pluto is not a planet. It is not because it is small, or it is ugly not round, but because it is not fulfill with the fourth law. Therefore, it is not one of the family.

2. There are two reasons that why Pluto does not belong to the solar system. Pluto may be a comet or half a comet, because A. Pluto is a alien, may come from other galaxies. B. Pluto may joint with a planet and a member of the other galaxies.

3. A planet cannot be discriminated because of their size, their mass, their radius, their color, or that they are ugly not round. As long as they fulfill with the fourth law. They are planets.
