Why Pluto is not a planet anymore?Pluto is not a planet anymore because it doesn’t fit into the new definition of Planets.
There are many objects in space which move around in our Solar system. These objects are precisely called as celestial objects. These celestial objects may or may not orbit our Sun. These objects may be big or small. They may have different composition and structure.
Based on their size, structure (shape), orbit (the path they travel), composition (what they are made up of), they are classified either as a Planet, Star, Dwarf Planet, Satellite, Comet or an Asteroid.
The designation of celestial object as a planet, comet or satellite is given by the International Astronomical Union (IAU). The International Astronomical Union consists of professional astronomers at International level who are responsible for classifying whether a celestial object is a planet or satellite or any other object.
