A NEW kind of planet, the "pluton", could soon be taking its place in the Solar System.

Astronomers have agreed on a draft proposal for redefining what constitutes a planet

If approved at a meeting underway in the Czech capital, Prague, school science text books will have to be re-written.

The new definition would mean there are 12, not nine planets, and more could be added to the list in the future.

They include eight "classic" planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune - Ceres, currently considered an asteroid, and three "plutons," one of which is Pluto.
