pluton
n.— «If the ideas are approved at the general meeting of the IAU in Prague next week, schoolchildren will, in future, have to learn that the solar system has 12 planets: eight classical ones that dominate the system—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune and Uranus—and four in a new category called plutons. These are Pluto, its moon Charon, a spherical asteroid that sits between Mars and Jupiter called Ceres, and an object called 2003 UB313 but nicknamed Xena by American astronomers who found it.» —“Pluto survives as solar system acquires three more planets” by Alok Jha Guardian (United Kingdom) Aug. 16, 2006.
