Take the grandkids to Adler’s “What Is a Planet?”


Most of the exhibits at Adler Planetarium in Chicago may be a bit beyond smaller kids, but if your grandchildren are older, they will likely find a lot to enjoy in the star shows and in a new exhibit called What Is a Planet? The show talks about what happened to Pluto-the-former-planet, but its main purpose is to highlight some of the museum’s prized historical icons relating to the evolving state of knowledge in astronomy.

When you visit What Is a Planet? you might even run into one of the Adler resident astronomers while you’re there. They love talking about astronomy and will tell you quite frankly that many astronomers disagree about a lot of things – another indicator of how our fund of knowledge about space is¬†always growing and changing.

FYI: The new definition of planet, voted on by members of the international astronomers union (many of whom disagreed!), is that it must a) have enough gravity to be round, b) rotate around the sun, and c) clear everything else out of its orbit, meaning asteroids and other such extraneous stuff cluttering up space.

Interested younger kids will like the exhibit also because, right across the hall from the 600-year-old book of calculations by Kepler and other fascinating artifacts from the Adler’s archives, is a Community Design Lab where kids can draw spaceships, imagine visits to planets, and create – to their hearts’ content – models of machines and dioramas of sci-fi scenarios. All drawing and construction materials supplied free of charge. The room is open from 10 a.m. to 3 p.m. each day.

P.S. No need to drive your car and pay a hefty parking fee. The #146 CTA bus drives directly into Museum Campus and pulls right up to the Planetarium. Catch it on Michigan Ave.
