Despite being the farthest planet from Earth in our solar system, Pluto has come under attack from astronomers and may be about to lose its status in the battle.

Some 3,000 astronomers and scientists from around the world are meeting in Prague to decide whether Pluto, discovered in 1930, measures up to the definition of a planet.

In defining for the first time what exactly a planet is, the International Astronomers Union (IAU) may be forced to downgrade Pluto's status, or add as many as 14 others.

Such a decision would send shockwaves through the scientific community, instantly outdate textbooks, and cause educators to re-teach the basics of our solar system.
