Solar Time, a Small Universe in the Browser

Field notes

Solar Time combines a real-time clock with a manipulable solar-system model, allowing visitors to pause, accelerate, or slow the displayed motion. Its quick guide specifies simulation ranges from one minute to twenty years and explains that planetary motion follows approximate elliptical orbits. The model includes Earth’s Moon and Jupiter’s Europa as child orbits, but explicitly omits long-term perturbations and fine distance changes, limiting it to visualization rather than precision astronomical prediction.
