TIPSHEET: The future of Pluto and Ceres
Three years ago, when the International Astronomical Union demoted Pluto to dwarf planet status, the unpopular decision was based on personal opinions and professional politics, not on rigorous scientific criteria that can clearly differentiate planets from lesser bodies, points out Vanderbilt astronomer David Weintraub. In the next decade, however, the amount of knowledge that we have about Pluto and another dwarf planet, Ceres, will change dramatically and this new information may affect our views of these objects and their status in the solar system as asteroids, dwarf planets or planets.
