"Send me to Pluto? Is it far?"

Scientists at the Rose Center for Earth and Space (American Museum of Natural History) have suggested that Pluto is not a planet at all, but rather a huge lump of ice.

Hundreds of chunks of ice and rock have already been discovered in what is known as the Kuiper Belt of comets - a disk of small icy worlds beyond the outer planets that includes Pluto and about 70 more with similar orbits.

Not everyone agrees that Pluto is not a planet. Many astronomers have said that unless there is more evidence to support that opinion, Pluto will remain one of the nine major planets in our Solar System.

When Pluto was discovered in 1930 it was thought to be about the same size as Earth. It is now thought to be smaller than our moon.

That's still a lot of ice to be drifting through space like an iceberg!
