Where the worlds are

Orrery

A top-down model of the solar system out to Pluto, positioned for a selected date from catalogue orbital elements. Distances use a square-root scale so the inner and outer worlds are both legible — it is not to scale.

Mercury — 0.453 AU from the Sun Mercury Venus — 0.728 AU from the Sun Venus Earth — 1 AU from the Sun Earth Mars — 1.627 AU from the Sun Mars Jupiter — 5.161 AU from the Sun Jupiter Saturn — 9.85 AU from the Sun Saturn Uranus — 20.04 AU from the Sun Uranus Neptune — 30 AU from the Sun Neptune Ceres — 2.545 AU from the Sun Ceres Pluto — 32.518 AU from the Sun Pluto

Positions use approximate two-body Kepler propagation. Accuracy varies by object and epoch; use JPL Horizons for precision work. Only bodies with usable positions are plotted. The circles show each body’s current radial distance, not its orbital path.
