What it means
Nothing about Pluto changed in 2006. What changed was the definition, after surveys began turning up similar bodies out beyond Neptune and it became clear that either Pluto was one of many or the list of planets was about to get long. The new definition asks that a planet have cleared its orbital neighborhood, and Pluto shares its region with a great deal of other material.
