Pluto	Pluto is a round object in outer space. Like our Earth, it moves around the sun. Scientists used to call Pluto a planet. It was the planet that was the smallest and farthest from the sun. But, now, scientists think Pluto is a little different from a real planet, and they don't call it a planet anymore.
