The expiation of this

. The OFFICIAL rules of I.A.U. states that a planet must a. Is in orbit around the Sun. Pluto does fulfill that rule.

b. Has enough gravity to keep it in a spherical shape. Pluto also fulfills that rule.

c. It must have sufficient gravity to have a CLEAR orbit. Pluto fails to meet the criteria.

If a planetary body fails to meet one of the three criteria it must be named as a dwarf planet. Pluto is officially a Dwarf Planet.
