The SAS is a purely professional Society devoted to development of astronomy in Serbia. The SAS has about 100 members, mainly from the Astronomical Observatory in Belgrade and from the Department of Astronomy of the University of Belgrade, but also from astronomical societies.
There are few members from other towns and several from abroad. The majority of members come from places where astronomy (and astrophysics) is taught either at the independent study group (Belgrade) or within the physics study group (Novi Sad, Nis, Kragujevac).

Before its foundation astronomers of Serbia were organized within the Society of mathematicians and physicists of Serbia (since its foundation in 1948) and by this Society within the Union of Societies of mathematicians and physicists (since its foundation in 1949). Both organization incorporated the astronomers officially in its title, in 1962 and 1966, respectively.
