NGC 6789, MCG+11-23-001, LEDA 63000 [1] |
NGC 6789 is a void [4] irregular galaxy in the constellation Draco. It was discovered by Lewis Swift on Aug 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]
