For whatever reason, I'm a little sad to hear this.
I have many fond memories of going to the Hayden Planetarium in NYC when I was growing up. It's undergone a massive renovation since I was last there, but I vividly remember the old permanent exhibits there and all the information about the planets. Will they will have to renovate again now that Pluto's been demoted?
Although this did make me smile a bit:
"It could be argued that we are creating an umbrella called 'planet' under which the dwarf planets exist," [astronomer Jocelyn Bell Burnell] said, drawing laughter by waving a stuffed Pluto of Walt Disney fame beneath a real umbrella.
