None. There are no "priveleges as a planet" to be stripped. And an inanimate object wouldn't miss them anyway. Pluto was recently stripped of its title as a planet. But it didn't lose any priveleges because of it.
Yes, it is a moon of Pluto, which is a Kuiper belt object.
Yes. PLuto is the largest known object in the Kuiper belt.
The Kuiper belt is not an object; it is a region of the solar system. Therefore it does not have an axis of rotation
No. Eris is not a Kuiper Belt object, but is instead part of the scattered disk, beyond the Kuiper Belt. Eris is slightly smaller than Pluto, though by an insignificant amount but has a greater mass, meaning it is denser.
The answer To Your Question Is Yes.
Pluto is the former planet that is now classified as a dwarf planet and a Kuiper Belt object. It was reclassified by the International Astronomical Union in 2006.
The Kuiper Belt is larger than a single asteroid. The Kuiper Belt is a vast region beyond Neptune filled with icy bodies and dwarf planets, while an asteroid is a much smaller rocky and metallic object typically found in the inner solar system.
Pluto's orbit is more elliptical than most Kuiper belt objects, it has a higher inclination relative to the plane of the solar system, and its composition is different from the typical Kuiper belt objects.
You would not have any particular weight "on" the Kuiper belt because it is not an object you can land on. The Kuiper belt is a region of the solar system that contains a collection of icy objects. You could potentially land on some of these objects, but you weight on them would vary depending on their size and mass. Some are too small to have noticeable gravity. The most massive of them, Eris, has about 8.4% of Earth's gravity.
Pluto is the former planet that is now classified as a Kuiper Belt object. In 2006, the International Astronomical Union redefined the criteria for planet classification, resulting in Pluto's reclassification due to its size and location in the Kuiper Belt, a region of icy bodies beyond Neptune. This decision sparked considerable debate within the scientific community and among the public.
Pluto is still considered to be the the largest KBO, however there are several "scattered" objects that are believed to have come from the Kuiper Belt. For a discussion of the sizes of known KBO's and Scattered KBO's see the related link
Makemake is an asteroid/Kuiper belt object in the outer solar system.
