Although I've been using my iPhone for a year now I've never felt the need to write a review before but this app is just amazing: simple and very useful. If you have a 3GS you can use the compass feature to identify your position in regards to the planets, look up and know exactly what planet you're looking at. It also tells you what time each planet is visible. To top it all off it's free! Definite download 5 stars.

Completed all levels with a handful of seconds to spare. Only 4 different environments and 8 challenges in total. Besides the short nature of the game I enjoyed it so 4 stars. Would have been 5 with more levels and openfeint achievments

Nothing to lose, try it out
