According to various rules, available for review by simple web searches, all planets except Pluto fell into the major planet camp. Thus, there are now eight instead of nine major planets. Although Pluto is now considered a dwarf planet, it isn't alone. Several large asteroids have found themselves promoted from "minor planets" to dwarf status. These include Ceres, the largest asteroid in the main belt between the orbits of Mars and Jupiter. Three other objects located even farther out than Pluto were designated dwarf planets as well: Haumea (2004), Makemake (2005), and Eris (2005). Depending on who you ask there are up to half a dozen or so other small worlds beyond Pluto — all discovered in the current century –— which should belong in the dwarf planet category as well.
