Calculated sky position

These are geocentric tropical sky calculations. Zodiac signs divide longitude into twelve equal sectors; they are not constellation boundaries. Their symbolic interpretation is separate from physical astronomy.

Technical calculation details

For reproducibility and advanced review.

Astronomical source
Astronomy Engine · 2.1.19
Time standard
UTC
Position reference
Earth-centred positions in the tropical zodiac, using the ecliptic of the calculation date.
Astronomical corrections
Planet positions account for light travel time and aberration; the Moon uses its geometric position.
Motion method
Forward or backward motion is measured from changes in calculated longitude.
