Planetarium for WiiWare is like a digital astronomy book…and even with the Wii’s weight included, probably weighs less.

Hudson has just revealed Planetarium, a WiiWare game that takes you through a virtual tour of the cosmos, encouraging you to look for stars and constellations along the way.

You may or may not be able to understand Japanese, but it’s basically a fun alternative to your massive astronomy textbook you carry around in your backpack on campus. Man…students have it easy today with games like this and Brain Age that always keep you on your toes.
