We know the numbers

Or at least have known them at some point, but a bit of occasional visualization goes a long way. Like in this fragment.

On a diagram of the solar system to scale, with the earth reduced to about the diameter of a pea, Jupiter would be over 300 meters away and Pluto would be two and half kilometers distant. On the same scale, Proxima Centauri, our nearest star, would be 16,000 kilometers away.
