Astronomers often want to know the physical mass of astronomical systems that they study. Some reasons are related to understanding the system’s structure and composition (What is the fraction of binary stars in a globular star cluster? Is there a central black hole at the center of a dwarf galaxy?), while others are related to answering fundamental questions of physics (How much dark matter is in a galaxy? How does dark matter affect the evolution of galaxies?).
