Pluto no longer a planet?

That's what the world's leading astronomers have decided today in a conference in Prague.

This is not the first time astronomers have "demoted" a heavenly body. Ceres, the biggest rock in the asteroid belt, was considered a planet until the 19th century.

So how does this affect us? Diddly squat.

I guess the foremost geeks in the world just wanted some attention.
