Our solar system is home to six official dwarf planets and counting. What is NOT one of them?

A dwarf planet has three main qualifications: it orbits the Sun, is nearly round due to its mass, is not a moon, and has not "cleared the neighborhood around its orbit". Pluto was once one of the nine planets in our solar system, but he got demoted to dwarf planet in 2006. The five others include Ceres, Eris, Makemake, Haumea, and most recently, RR245.
