Big Floating Rocks in Space

According to an article in The Economist, Pluto’s planetship is currently being debated. Apparently the Kuiper-belt contains thousand of objects that may or may not be planets, and Pluto is one of those objects. Pluto is less than 1% of the Earth’s mass, and there is an object discovered in the belt that is larger. So now the astronomers are rethinking the definition of a planet. Hope we stay on the list!
