It is no longer the ninth planet in the solar system. They labeled it a dwarf planet along with a larger object named Eris. Both objects are located in a zone beyond Neptune called the Kuiper Belt. Dwarf planets are much smaller than the other eight planets. Pluto was the only planet discovered by an American. An astronomer from Kansas named Clyde Tombaugh found it. He had carefully compared photos of an area of space beyond Neptune. This area was thought to contain a ninth planet. He spent more than 7,000 hours over more than two years comparing photographs of light. He was trying to discover the movement of a planet against the background stars. On February 18, 1930, Tombaugh discovered this movement. An eleven-year-old English schoolgirl won a contest to name the planet. She suggested Pluto, who is the god of the underworld in ancient myths. Why was Pluto removed from the list of major planets? In a word—size. Charon, a moon orbiting Pluto, was discovered. It was about half the size of Pluto. Moons are not that large compared to the planets they orbit. Scientists were also able to determine Pluto’s actual size, which was quite a bit smaller than originally thought. Pluto was found to be smaller than several moons, including our own. Its orbit was also very different from the other planets. Pluto is, of course, still there. It just doesn’t have as big of a reputation anymore. Scientifically Speaking Download 10.24 Kb.
