The main role of the Society is popularisation of astronomy. The Society also practices amateur astronomy observations. To accomplish this, in 1964, the Society founded the Public Observatory, which is still located in adapted Despot's Tower in Kalemegdan, Belgrade. The Belgrade Planetarium, one of the only two planetariums in Serbia, is also founded by the society, in 1970. It is located in the lower part of Kalemegdan Fortress, in a former Turkish bath.

Works began in May, instruments were to be installed by autumn, and the observatory was to become operational in October 1963. Today, the tower is the seat of the Astronomical Society Ruđer Bošković and houses its Popular Observatory. The Observatory has two instruments: refractor Zeiss (110/2200mm) and reflector Tall 200 K (200/2200mm), both of which are used mainly for observations at night.

Stars And Atoms
A star is an astronomical object comprising a luminous spheroid of plasma (physics), plasma held together by its gravity. The List of nearest stars and brown dwarfs, nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night sky, night, but their immense distances from Earth make them appear as fixed stars, fixed points of light. The most prominent stars have been categorised into constellations and asterism (astronomy), asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye, all within the Milky Way galaxy. A star's life star formation, begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements.
