The following animated visualization takes the viewer on a 10-minute journey from the Sun to the planet, Neptune. It creates a hypothetical moment in our solar system whereas all the eight planets would align in one straight line and that one could travel directly to Neptune.
This video is intended to demonstrate that even given a short amount of time, the distance to the outer planets of our solar system, and from the earth and sun, is very vast. This movie also includes additional tidbits of information as your are waiting on time between planets.
