Our Solar System now includes 12 planets, with more to come: eight classical planets that dominate the system, three planets in the Plutons category (Pluto, Charon and the so called “2003 UB313″) and Ceres. Pluto remains a planet and is the standard for the new category of plutons. Plutons are Pluto-like objects.
