International Astronomical Union (IAU)

The International Astronomical Union (IAU) is a global organization of professional astronomers dedicated to promoting and coordinating astronomical research, education, and standards. Founded in 1919, it facilitates international collaboration, defines celestial naming conventions, and establishes official classifications for astronomical objects like stars and planets. The IAU ensures consistency and clarity in astronomical communication, such as the official naming of planets and moons, and supports scientific progress by fostering cooperation among astronomers worldwide. It plays a vital role in maintaining the precision and integrity of astronomical data and discoveries.
