4D2U is pretty cool project which allows you to surf around the solar system and get to know about each planet and details on how big it is and many more. Its a 4D view where you can move in and out of The whole galaxy . Here is what they say :

The project’s goal is to visualize astronomical data in a way that helps watchers feel as if they are witnessing the unfolding of the universe. “Four dimensions” refer to the three dimensions of space and the one dimension of time embedded in their data. “Digital” refers to computer graphics visualizations of digital data. The resulting acronym is “4D2U”, and it is also astronomy’s way of saying “4D to you.”

So what are you waiting for go and take a tour of our galaxy
