Pluto has officialy been stripped of it's status as a planet. First discovered in 1930 by American born Clyde Tombaugh, Pluto has had it's status downgraded to 'Dwarf Planet'. This has happened due to the IAU's revision of what defines a planet, from a large piece of rock hurtling through space and time. Sounds like fun doesn't it! Not really, and it certainly wasn't for the 2500 experts who've spent the last week voting on definitions, downgrades, upgrades, and whatever else they think matters to the world. Neptune may also be demoted from a planet into a dwarf planet aswell, but only if the IAU members vote for it to be. This is because it also doesn't meet the 'planet' criteria. The new definitions mean that 3 other objects may be classed as planets. These include the asteroid Ceres, Pluto's moon Charon, and a distant world called 2003 UB313.
These new revelations are throwing the whole astronomical world into turmoil, and it's not yet clear how the battle will end.
