Pluto kicked out of the planets

Pluto has lost its status as the ninth and outermost planet of the solar system, the world's leading astronomical body has decided.

After a heated debate, 2,500 scientists and astronomers voted at the International Astronomical Union (IAU) on Thursday that Pluto, which has been called a planet since being discovered in 1930, would be put into a category called "dwarf planets".

The IAU resolution said: "The eight planets are Mercury, Earth, Venus, Mars, Jupiter, Saturn, Uranus and Neptune."
