The seasons of the year are an astronomical topic of great relevance to geographical studies. Approach the seasons from the Earth's surface requires understanding of the apparent annual movement of the Sun on the celestial sphere. It is a broad subject that, in most cases, is not satisfactorily understood by students or even by teachers. Several studies have pointed to various problems about the teaching and learning of the seasons. The causes range from poor training of teachers regarding astronomical themes to the high level of abstraction that these contents require in order to be understood. On the other hand, the planetariums constitute prime locations for the (re)construction of knowledge, because they meet appropriate conditions for pedagogical practice of topics involving the celestial phenomena. This is a space whose function is the teaching and dissemination of interdisciplinary scientific knowledge, being the astronomical more evidenced. In this perspective, we conducted a case study within the Planetarium of UFG whose general objective is to investigate, through the learning of students evaluated, if really this space science is effective for teaching the seasons of the year and what are their contributions in this context, whether they are positive or not. The Planetarium of UFG has an optical-mechanical projector with topocentric reference, in other words, a system of reference centered at the place of observation, on the Earth's surface. The empirical work involved 56 students through the application of two questionnaires directly related to a class held inside the dome of the planetarium. It was found that 24 students have achieved a good learning at the summit, 19 had a median learning and 13 had a poor learning. Although they remained several conceptual confusions, the lesson in the dome provided students with the development of a more decentralized and reversible reasoning of spatial relations between the observer and the directions of the geographical space, indicated by apparent annual movement of the Sun in the sky. Thus, we intend to discuss throughout this work the capacity of the Planetarium of UFG have to contribute to the learning of the seasons through the topocentric reference, making conceptual changes from the previous ideas found in students investigated.
