Google earth is a 3d program that you download in your PC. It's features are:

~3D visions of Earth, Space,different Planets, and stars.

~ Will name the moons craters.

~Has street level view. (I saw what went on in China,Japan,Tokyo,and Asia! On The street!!)

Some features you may want to look at before downlading:

~ It is not a map, so dont try to track or map anything, thats google maps.

~ It may take lots of space, so make sure you have that amount or your PC will CRASH!!!!
