Your kids may act like they come from Planet Nose Picker.

But you can teach your little space case something about the real cosmos with the Remote-Controlled Solar System Mobile by Uncle Milton. Perfect for late-night fun, the mobile has a light-up sun around which nine planets slowly orbit.

It even comes with an audio CD that takes you on a tour of the solar system and a light pointer so Junior can navigate the way from Mars to Pluto.

Now that’s out of this world.

Available at the Infinity Shop, Adler Planetarium, 1300 South Lake Shore Drive, at McFetridge Drive (312-322-0312 or adlerplanetarium.org).
