masses in astronomy

While mass is surely one of the most basic properties of an astronomical object, it is not that easy to actually determine that mass. Most methods utilize the laws of celestial_mechanics to deduce from the way that two (or more) objects orbit each other their respective masses. In other cases, relativistic effects such as the deflection of light or the Shapiro delay can be used to determine an object's mass.
