DistanceToSun.com is an interactive visualization designed to show the true scale of astronomical distances by drawing two bodies at the correct relative size and placing them at the correct distance apart.
The slider controls the right-hand body and always starts at 1 pixel. The left-hand body and the distance update live at the same scale.
The main site (Sun–Earth) supports Astronomical Units (AU), perihelion (closest approach), and aphelion (farthest distance). The planet and Moon sub-sites support closest and farthest distances.
