Number of planets set to rocket
It looks like school books will have to be re-written as space experts are set to overhaul our Solar System!
The number of planets around the Sun could rise from nine to 12 - and that number may even rocket!
Experts are re-thinking what should be called a planet because of the discovery of space objects bigger than our smallest planet Pluto.
In a new proposal, these objects would become planets, but they would be called plutons.
Plutons would include Pluto, its moon Charon, a new object UB313, which is nicknamed Xena, and the largest asteroid Ceres.
About 3,000 astronomers are meeting in the Czech Republic and the final decision will be made on 24 August.
The new plan would see eight ordinary 'classical' planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune - and four plutons - Pluto, Charon, Xena and Ceres.

Plutons would differ from ordinary planets in that they have orbits round the Sun that take longer than 200 years to complete and their orbits are not circular.
New category
Top space expert Professor Owen Gingerich said: "In a sense we're demoting Pluto by taking it off the list of classical planets.
"But we're promoting it by making it the prototype - the first of its kind - of this new category of plutons."
