NGC 3109 is a small barred spiral galaxy around 4.3 Mly away in the direction of the constellation of Hydra. It is the most prominent member of a Local Group subgroup. NGC 3109 is believed to be tidally interacting with the dwarf elliptical galaxy, Antlia Dwarf.[5] It was discovered by John Herschel on March 24, 1835 while in South Africa.[4]
