Rotation of Planets

Notices

• B₀ and L₀ are planetographic latitude and longitude of the sub-Earth point, respectively. B_s and L_s are planetographic latitude and longitude of the sub-solar point, respectively.
• P and P_s are the position angle of the planetary rotation axis (North Side) and the sub-solar point, respectively, as seen from the Earth and measured from celestial north, positive being eastward and negative being westward.
• i is the phase angle and k is the fraction illuminated.
• V is the apparent magnitude of the planet.
• B'₀ and B'_s are planetocentric latitudes of the sub-Earth point and sub-solar point, respectively.
• λ_s is the solar longitude in the ecliptic of the planet.
• Limitation of one calculation is either 370 days or 400 cycles.
