Why is Pluto no longer a planet? In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of dwarf planet.. This means that from now on only the rocky worlds of the inner Solar System and the gas giants of the outer system will be designated as planets.
American astronomer Clyde Tombaugh discovered Pluto in 1930. From 1930 until 2006, Pluto sat comfortably beyond Neptune as the ninth planet in our solar system. In 2006, however, changes were made. The truth is, nothing about Pluto changed, but the definition of a planet did. Once these changes became official, Pluto no longer fit the definition of a planet.
