Icy Ball Xena Is Larger Than Pluto

So Is It a Planet?: “A ball of ice and dust discovered last year in the outskirts of the solar system is 30 percent wider than Pluto, a team of German astronomers is reporting today.

The finding definitively makes the icy ball — temporarily labeled 2003 UB313 and nicknamed Xena — the largest known object to be discovered orbiting Earth’s sun since Neptune was identified in 1846, and adds to the debate over what should be considered a planet.” (New York Times)
