Difference between Planets beyond Neptune and Pluto

Planets beyond Neptune vs. Pluto

Following the discovery of the planet Neptune in 1846, there was considerable speculation that another planet might exist beyond its orbit. Pluto (minor planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune.
