Pluto, which was once considered the ninth planet in our solar system, was reclassified as a 'Dwarf Planet' by the International Astronomical Union (IAU) in 2006. This reclassification was based on a new definition of what constitutes a planet, which Pluto no longer met. According to the IAU's definition, a planet must meet three criteria:

It must orbit the Sun.
It must be spherical in shape, meaning it has enough mass for gravity to pull it into a nearly round shape.
It's orbital path must be cleared of neighbours.
While Pluto meets the first two criteria, it does not meet the third one because its orbit overlaps with that of other objects in the Kuiper Belt, a region of the solar system beyond Neptune that contains many small, icy bodies.

As a result, Pluto was reclassified as a dwarf planet, and the solar system was left with eight recognized planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. It still remains an object of Scientific interest tho.

" is a complex world of ice mountains and frozen plains. Once considered the ninth planet, Pluto is the best known of a new class of worlds called dwarf planets"-
