Real Time Solar System, With a Date Scrubber

Field notes

The simulation runs in the browser and exposes a time scale from 3000 BC to AD 3000, with playback controls and optional true-orbit, trail, label, and grid views. Alongside the visual model, the site maintains practical reference sections for eclipses through 2050, lunar phases and apsides, ISS passes, launches, and nighttime visibility from 86 cities. Its methodology names VSOP87, an ELP-derived lunar series, Astronomy Engine, and stated comparisons with NOVAS and JPL Horizons.
