Earth and Sun (celestial coordinate system)

This activity belongs to the GeoGebra book Earth and Sun. This activity will help you visualize the apparent path of the Sun throughout the year and its consequences, such as the length of the day or the passage of seasons. You can choose from five menus: References, Time, Celestial Coordinates, Coordinates A, and Apparent Trajectory. For better execution, and to be able to scale the sphere, it is recommended to download the GGB file.
