Planet Rise and Set Calculator
Calculates the times of planetary rise and set, azimuths, and times of meridian passage and altitudes as seen from Earth.
Enter western longitudes and southern latitudes as negative values.
Azimuths are measured as North: 0 degrees, East: 90 degrees, South: 180 degrees, and West: 270 degrees.
This calculation assumes a flat horizon and does not take specific terrain features into account.
Calculation results may contain errors of a few seconds, which increase at higher latitudes.
