Description |
NGC
4945 is a rather chaotic looking
barred spiral galaxy
in Centaurus discovered by James
Dunlop in 1826. It's one of the
brightest galaxies in the
Centaurus A/M 83 group. Given
its low galactic latitude it is
much obscured by dust giving it
a distinctive reddish colour.
The obscuration is estimated to
be about 1 magnitude. The
distance is about 11.7 million
light years, the apparent
magnitude is 9.3 and the
apparent size is 20 x 3.8
arcminutes. |
