Sides: $PZ = 90^\circ - \phi$ (co-latitude) $PX = 90^\circ - \delta$ (polar distance) $ZX = 90^\circ - a$ (zenith distance)

Spherical astronomy, or positional astronomy, uses spherical trigonometry to determine the locations of celestial objects. Below are core concepts followed by common problems and their step-by-step solutions. Core Mathematical Tools Spherical Cosine Rule : For a spherical triangle with sides and opposite angles spherical astronomy problems and solutions

Using the Cosines and Sines rules combined with your local Sidereal Time. This math accounts for your specific latitude and the exact moment you are looking up. 3. The "Wobbly Earth" (Precession and Nutation) Sides: $PZ = 90^\circ - \phi$ (co-latitude) $PX
