Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.
In a draft resolution for the IAU definition of planet, both Pluto and Charon were considered planets in a binary system. [20] [c] The IAU currently says Charon is not considered a dwarf planet but rather a satellite of Pluto, though the idea that Charon might qualify as a dwarf planet may be considered at a later date.

Pluto, a dwarf planet that typically orbits outside Neptune, is vastly small in comparison to Jupiter, and much farther away. The Jovian–Plutonian gravitational effect was a hoax phenomenon purported to cause a noticeable short-term reduction in gravity on Earth that was invented for April Fools' Day by the English astronomer Patrick Moore ...
Pluto was considered a planet up until 2006, when researchers at the International Astronomical Union voted to "demote" it to dwarf planet.
For 76 years, Pluto was considered our solar system's ninth planet — so, ... For 76 years, Pluto was considered our solar system's ninth planet — so, what caused it to lose its status?

While the majority of plutinos have relatively low orbital inclinations, a significant fraction of these objects follow orbits similar to that of Pluto, with inclinations in the 10–25° range and eccentricities around 0.2–0.25; such orbits result in many of these objects having perihelia close to or even inside Neptune's orbit, while ...
It is about half the diameter and an eighth the mass of Pluto, a dwarf planet that resides in a frigid region of the outer Solar System called the Kuiper Belt, beyond the most distant planet ...
