TThe International Astronomical Union IAU (Union astronomique internationale 
(UAI), in French) is a collection of professional astronomers, at the Ph.D. 
level and beyond, active in professional research and education in astronomy. It 
acts as the internationally recognized authority for assigning designations to 
celestial bodies (stars, planets, asteroids, etc.) and any surface features on 
them, and is a member of the International Council for Science (ICSU). The main 
aim of the IAU is to promote and safeguard the science of astronomy in all its 
aspects through international cooperation. The IAU maintains friendly relations 
with organizations that include amateur astronomers in their membership. The IAU 
has its head office in Paris. IAU was founded in 1919.
