In the Fall Semester, we look at the physics of gravitational motion and apply what we learn to a succession of gravitating systems with increasing numbers of bodies, at increasing distances from Earth: planets, binary stars, open and globular clusters of stars, galaxies, clusters of galaxies, and the Universe as a whole. We also look at the astronomer's tools: telescopes and their detectors.
