| Object type: | Galaxy (dwarf Irr) | |
| Size: | 15.4' x 14.2' | |
| Magnitude: | 9.3 mag | |
| Constellation: | Sgr | |
| Distance: | 1.6 Mio Ly | |

NGC 6822 was discovered by E.E. Barnard in 1884. This irregular dwarf
galaxy is a member of the Local Group.
There is much dust in this region of the sky, as can be seen clearly in the inverted image. The dust is a part of our Milky Way. Because we are looking through this dust at Barnard's Galaxy, the colour of NGC6822 is more reddish than it would have been without dust: E(B-V)=0.24 mag. |
