NGC 6789 is a void[4] irregular galaxy in the constellation Draco. It was discovered by Lewis Swift on August 30, 1883.[5] It is located within the Local Void, a region of space with far fewer galaxies than its surroundings.[4]
NGC 6789 is the nearest blue compact dwarf (BCD) galaxy to the Milky Way. It is chemically homogeneous and relatively metal-poor.[3]
NGC 6789 has attracted attention because it shows recent central star formation despite its extreme isolation.[6]
