For those of us who believe dwarf planets should be counted as a subclass of planets, the latest status is that our solar system now has 13 planets: four terrestrial planets, four jovian planets, and five dwarf planets.
Ceres, the largest asteroid in the main asteroid belt between Mars and Jupiter, was also declared a dwarf planet. The three other (for now!) dwarf planets are Eris, Makemake, and Haumea. Pluto, Makemake, and Haumea orbit the Sun on the frozen fringes of our Solar System in the Kuiper Belt.
