Solar system, shrunk to a street

If one AU (the Earth to Sun distance, 150 million km) were one meter, here is how the solar system lines up.

Walk outward from the Sun

One meter on this chart is one AU, the Earth to Sun distance. Slide to walk. The chart is stretched with a log scale so Mercury and Neptune both fit, so the rings aren't evenly spaced.

    Planet distances: NASA planetary fact sheet (mean distance from the Sun). Jet speed 900 km/h, Voyager 1 about 17 km/s. A step is counted as 0.75 m. The Sun is a 9.3 mm bead on this scale and Earth is a 0.09 mm speck, too small to draw.

    In human terms

    • On this scale the Sun is a 9.3 mm bead and the Earth a 0.09 mm speck.
    • The Milky Way is about 100,000 light years across. At this scale that's roughly 6.3 million km, or about 16 times the real Earth to Moon distance.
