Abstract: Density and internal structures are among the most critical characteristics of asteroids, yet these properties are also some of the least known. For distant asteroids (in the Main Belt and beyond), they were, until now, accessible only for some of the largest (>100 km in size) asteroids. Going to smaller and fainter asteroids can revolutionize our understanding by sampling a new regime in physical properties. Here we discuss how asteroid satellites can be observed by ground-based interferometers and the data that can be obtained. This is the most accurate approach for measuring the mass of an asteroid without a spacecraft.
