Astronomical Algorithms (Jean Meeus)

This page introduces the computational foundations used across AstroAlgos. All celestial positions and visualizations are computed using the methods from Jean Meeus' book "Astronomical Algorithms".

Core topics implemented on the site

• Julian Day: time axis used in astronomy
• Dynamic Time (ΔT): UT vs atomic time and estimates
• Precession: long-term motion of equinox
• Semidiameter: apparent angular radii
• Constellations: 3D sky coordinates
• Topocentric coordinates: sky from your location

Wherever possible, numerical outputs are cross-checked and the sources are cited for transparency.
