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.

How does star blow up ?

A hot bright star blows up when it runs out of fuel.

Here's why that happens. The force of gravity is always puling the matter in the star toward the center. But in that center, small bits of matter called atoms are always fusing together, making bigger atoms and releasing huge amounts of energy. That energy pushes outward and works against the gravity during the star's life. After many millions of years, the star runs out of small atoms. Then it has no more energy to push outward. The star collapses, and when the matter collides in the center, it explodes.
