The American Astronomical Society (AAS, sometimes spoken as "double-A-S"[citation needed]) is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community.

The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the society was not finally decided until 1915, previously it was the "Astronomical and Astrophysical Society of America". One proposed name that preceded this interim name was "American Astrophysical Society".[1]
The AAS today has over 8,000 members and six divisions – the Division for Planetary Sciences (1968), the Division on Dynamical Astronomy (1969), the High Energy Astrophysics Division (1969), the Solar Physics Division (1969), the Historical Astronomy Division (1980) and the Laboratory Astrophysics Division (2012). The membership includes physicists, mathematicians, geologists, engineers and others whose research interests lie within the broad spectrum of subjects now comprising contemporary astronomy. The annual meeting of the AAS is held in the spring and constitutes the largest gathering of astronomers, numbering over 3,000 in 2023.[2]
In 2019 three AAS members were selected into the tenth anniversary class of TED Fellows.[3]
The AAS established the AAS Fellows program in 2019 to "confer recognition upon AAS members for achievement and extraordinary service to the field of astronomy and the American Astronomical Society."[4] The inaugural class was designated by the AAS Board of Trustees and includes an initial group of 232 Legacy Fellows.[4][5]
Because the field of astronomy is diverse, several divisions have been formed each of which promotes and enables a different branch of astronomy or astronomy-related science as well as working within the overall charter of the AAS. Many of the divisions hold separate meetings in addition to meeting with the main group. The divisions of the AAS, together with their main research interests, are:
Similar prizes are awarded by AAS divisions. These include:
The AAS also manages an International Travel Grant program, which any astronomer working in the US may apply to for travel to international astronomy-related conferences and other smaller grant and award programs. American Astronomical Society won the 2020 Webby People's Voice Award for Association in the category Web.[8]
