The Adler already has a planetary anachronism. When it opened 76 years ago, plaques had already been commissioned for just eight planets. Pluto was discovered a few months laterGyuk doesn't see the Adler adding plaques for Pluto or the three proposed planets because "we just don't have space."
For the several thousand planetariums around the world, this is more exciting than difficult, said Susan Reynolds Button, president-elect of the International Planetarium Society.
"It's not a problem," Reynolds Button said. "We already have the visuals. We already have the equipment to do it. It's just a matter of presenting new data."
Reynolds Button, who used to take planetarium shows to schools, said the addition of three new planets "is a real nice juicy topic to get kids excited about."
Dan Reidy, a sixth-grade science teacher in Moultonborough, N.H., was sitting in his classroom preparing for the new school year and gazing at his model of the solar system. He usually asks his students, "What's wrong with this picture?" The correct answer is that the planet sizes and their distances from the sun are all out of proportion.
If the planet lineup changes, there will be something else wrong with his model.
Reidy will also have to figure out where to place the new planets on a large parachute-cloth solar system map that demonstrates proper size and scale, but he said it was exciting.
The race to change solar system toys more permanently is already on.
Discovery Channel Store spokeswoman Pamela Rucker predicted new 12-planet toys could be in stores in time for the Christmas season.
"We're already starting to work on 12 planets," said McLynn of Learning Resources.
