how did planet pluto destroyed ?

Pluto was discovered, scientists thought it was a planet. However, as its estimated size became smaller and smaller, doubt began to slowly rise on whether Pluto is actually a planet. Many objects that are also orbiting alongside Pluto didn’t help its status either. This actually happened before, when Ceres was discovered and considered a planet before many objects were discovered to also orbit alongside Ceres, and since scientists didn’t want the Solar System to have 100 or even 1000 planets, Ceres and other objects alongside it were demoted to asteroids, forming the asteroid belt. This time, scientists coined the term ‘dwarf planet.’ Pluto was demoted to a dwarf planet, Ceres was semi-promoted to an asteroid-dwarf-planet mix, other objects alongside Ceres were still asteroids, objects alongside Pluto were considered TNOs (Trans-Neptunian Objects).
