Pluto No Longer Planet! Mickey, Donald Next?

Models of the planets in our solar system are suspended around the Hayden Sphere at the American Museum of Natural History’s Rose Center for Earth and Science in New York earlier today. When the museum constructed the model, it left Pluto out because scientists at the museum did not consider it a planet. Now it’s official. The International Astronomical Union stripped Pluto of its status as a planet today. (Shino Fukada/AP Photo)
