Scientists at the Rose Center for Earth and Space, part of the American Museum of Natural History in New York, have made a startling new assertion, by claiming that Pluto is no planet, only a chunk of ice.
They have a display of the solar system which includes only 8 planets, and reads "Beyond the outer planets is the Kuiper Belt of comets, a disk of small, icy worlds including Pluto." There has been controversy for some time over Pluto's nature.
Many feel the museum has gone too far. "Tyson is so far off base with Pluto, it's like he's in a different universe. The majority of astronomers have said that unless there is definitive evidence to the contrary, Pluto stays a major planet."
