For example, I heard somewhere, something about Pluto not being a planet. How can it be a planet for so long and all of a sudden NOT be a planet? I didn't look into it so I don't know if they are actually not considering it a planet anymore, or if some jerk off reporter misunderstood what someone said, and ran with it.
As I understand it, the definition of a "planet" was never all that well formalized, and now that other outer-orbit objects have been found, it was decided that a proper definition had to be found. That definition would either have to include several of these other objects, or exclude Pluto, and it was decided to do the latter. So it's not that Pluto has changed, it's just that the scientific term "planet" has now been more rigorously defined... and it doesn't cover this eccentric little ball of rock, sorry Greek god of the underworld.
