In this document we describe the necessary constructions for modeling the apparent position of the Sun in the sky in GeoGebra. We discuss how to build a planet that moves and rotates about its axis and a way to position the observer at a given latitude from which we will compute the horizontal coordinates of the Sun. Later these computed coordinates are represented in a celestial sphere where the horizon plane for the observer is fixed, giving the apparent track of the Sun at different days of the year.
