What type of celestial body is Pluto classified as?

What type of celestial body is Pluto classified as?

• A. Planet
• B. Dwarf planet
• C. Asteroid
• D. Comet

Answer: (B)

Pluto is classified as a dwarf planet because it meets specific criteria established by the International Astronomical Union (IAU) in 2006. To be recognized as a dwarf planet, a celestial body must orbit the Sun, be spherical in shape due to its own gravity, and not have cleared its orbital neighborhood of other debris. While it orbits the Sun and has sufficient gravity to maintain a spherical shape, Pluto does not dominate its orbit, as it shares its space with other objects in the Kuiper Belt. This unique status distinguishes it from the eight recognized planets in our solar system, which do clear their orbits. The classification highlights the diversity of celestial bodies in our solar system and reflects ongoing discussions in planetary science about the characteristics that define different types of objects.
