A working group is expected to recommend to the International Astronomical Union (IAU) that Pluto be retained as a planet, opening the door for other solar system objects to also be designated as planets. NPR reported this week that the group will likely report at an IAU meeting later this month in Prague that Pluto retain its designation as a planet, and that a new class of planets, perhaps called "dwarf planets", be created. That class of planets would include Pluto, possibly the largest asteroids, and a number of the new large objects discovered in the outer solar system. Pluto's classification as a planet has been questioned for the last several years as large icy bodies in the Kuiper Belt and beyond have been found. At least one of those objects, nicknamed Xena, is now believed to be larger that Pluto.
