Explanation:

The new definition of a planet adopted by the International Astronomial Union (IAU) during its week long discussion at Prague in the Czech Republic on August 24, 2006 was as follows Planet: A planet is celestial body that:
(a) Is in orbit around the sun.
(b) Has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrstatic equillibrium shape.
(c) Has cleared the neighbourhood around its orbit.
(d) Should be as effective around the sun as other planets.
According to the above definition, pluto has lost its status as a planet and is demoted to the status a dwarf planet.
