Here's why:
* Location: Pluto resides in the Kuiper belt, a region beyond Neptune populated by icy bodies.
* Composition: Pluto's composition is similar to other Kuiper belt objects, consisting primarily of ice and rock.
* Orbit: Pluto's orbit is highly eccentric and inclined, a characteristic shared by many Kuiper belt objects.
The idea that Pluto is not a Kuiper-belt object is a misconception that stems from its former classification as a planet. However, the International Astronomical Union (IAU) reclassified Pluto as a dwarf planet in 2006 due to its size and the existence of other similar objects in the Kuiper belt.
Therefore, there is no evidence or argument that contradicts the fact that Pluto is a Kuiper-belt object.
