@article{Cederbloom_2024, title={Finding distances I}, volume={4}, url={https://pac.pogil.org/index.php/pac/article/view/367}, abstractNote={<p>Finding distances I is an introduction to finding distances to astronomical objects. There are three parts: size and angular size, the small angle formula, and the standard ruler method for galaxies. The learning objectives are to understand the relation between angular size and distance, to derive the small angle formula, and to apply the small angle formula to galaxies.<br /><br /></p>
