Visualization of New Horizons Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of New Horizons with respect of the Sun and the orbits of the major planets. The position of New Horizons and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!
