"Eyes on the Solar System" is a 3-D environment full of real NASA mission data. Explore the cosmos from your computer. Hop on an asteroid. Fly with NASA's Voyager spacecraft. See the entire solar system moving in real time. It's up to you. You control space and time.
This is a really neat new online application where you can zoom around the solar system and see objects such as satellites and asteroids, including 2012DA14! Scientists on NASA TV covering the near-Earth approach mentioned it
