How it works

This simulation uses NASA JPL's DE405 ephemeris data (via astronomy-engine) to calculate the precise angle of each planet relative to the Sun right now. While the distances between orbits are scaled down for visibility (a "schematic" view), the angular positions are astronomically accurate.

Planetary Alignment

Planets orbit at different speeds. Mercury zips around every 88 days, while Saturn takes 29 years. This map helps visualize why some planets are visible in the evening sky (east of the Sun) or morning sky (west of the Sun).
