Pluto Demoted – Not Disney Character

The vote involved just 424 astronomers who remained for the last day of a meeting of the International Astronomical Union in Prague.

As of today, Pluto has been demoted and is no longer considered part of the “planets” of the solar system. Our solar system is in the Milky Way galaxy of the universe. (FYI)


Years of Debate:

Astronomers have argued since the late 1990s on whether to demote Pluto. Public support for Pluto has weighed heavily on the debate. Today’s vote comes after a two-year effort by the IAU to develop a definition. An initial committee of astronomers failed for a year to do so, leading to the formation of the second committee whose proposed definition was then redefined for Thursday’s vote.

The question that remains is how is this going to affect schools and children growing up trying to understand how when they left second grade there were 9 planets and in third grade there are 8 planets. How are children going to realize that what we have known for years is now changing? I guess it is the same situation when they thought that the earth was the center of the solar system. We live in a dynamic world and we need to adjust, but I hope too many “facts” don’t change.
