| Designation | NGC 4945, Bennett 57 |
| Object type | Spiral galaxy |
| Coordinates | 13h05m - 49°28' |
| Constellation | Centaurus (Cen) |
| Description | For such a close galaxy, NGC 4945
is easy to miss. NGC 4945 is a spiral galaxy in the Centaurus
Group of galaxies, located only six times farther away than the prominent
Andromeda Galaxy. The thin disk galaxy is oriented nearly edge-on,
however, and shrouded in dark dust. The yellowish/red
appearance is caused by about 1 mag of interstellar absorption due to its
low galactic latitude. Together with NGC 5128
(Centaurus A) and M 83, it
forms part of a small group of galaxies 13 million lightyears away.
