Trying to locate an app I found once.. Displays the Solar System.

I found this app the other day, however I was not on my computer that I use the itunes store from.

I can't seem to find the app anywhere. What it allows you to do is view the solar system and see where everything will be facing, whats moving and if there is a full moon.

Any ideas? On the reviews people were saying its one of the best apps and the graphics were amazing.

think thats it.. thanks!
