Being the Astronomy one of the oldest sciences of the humanity, and considering its historical and cultural importance, it is of extreme relevance that topics related to it are taught and studied at schools. Although the National Curriculum Parameters of the Senior High School (PCN-EM) and the Complementary Orientations to the Parameters (PCN+) indicate the importance of a significant approach of concepts related to the Astronomy in the Physics classes, many students finish the Senior High School (EM) without understanding the reason of certain events of celestial origin, although these are part of their daily lives and are a subject of natural curiosity for the youngsters. From the perception of the natural curiosity of the students of a São Paulo's Public School in the city of Suzano, came up the interest to investigate the basic knowledge in Astronomy of the Senior High School students at this school, becoming this the main goal of this research. A questionnaire of multiple choices was elaborated and initially applied to 34 students of the first grade and later, to more 310 students. It was distributed among the three grades of the Senior High School in the morning and night periods. In the way, it was observed that 73.9% of the students identified the Sun as a star, 67.1% demonstrated to understand the succession between the day and the night and 52.3% related the Big Bang to the origin of the Universe. In compensation, only 34.5% related the seasons of the year to the inclination of the rotation axis of the Earth, 21.3% indicated the simultaneous gravitational influence of the Moon and the Sun as responsible for the tides phenomenon, 24.5% correctly indicated which are the closest celestial objects to the Earth, 36.1% identified the light-year as a distance measure and only 34.2% recognized the shooting stars as meteors, being evidenced the small discernment of the students about the phenomena and astronomical terms of the daily life. Besides, the answers of different grade students and periods were compared, being observed, among other things, that the third grade students present a percentile of correct answers similar to the performance of the first grade students, demonstrating that the approach of topics related to the astronomy in the Senior High School has not been contributing in a significant way to a better understanding of the phenomena and the concepts.
