Discovered by E.E. Barnard in 1884.

NGC 6822 was discovered by E.E. Barnard on August 17, 1884 with a 6-inch refractor (Barnard 1884). This is an irregular member galaxy of the Local Group, as was recognized by Hubble and Humason in the 1920s. It was the third galaxy beyond the Magellanic clouds where Cepheid variables have been found, after M31 and M33 (Hubble 1925).
