NGC 3109 is a small barred Magellanic type spiral or irregular galaxy around 4.35 Mly away in the direction of the constellation of Hydra. It was discovered by John Herschel on March 24, 1835 while he was in what is now South Africa.
NGC 3109 is generally considered a member of the Local Group, specifically as the dominant galaxy in its own small, outlying subgroup, though its status is sometimes debated due to its edge-of-group position.
