| Description | NGC
5102 is another galaxy in the
group that includes M83 and NGC
5128. It is relatively bright at
magnitude 10.4 and is 8.7 x 2.8
arcminutes in size. It's about
12.1 million light years away.
NGC 5102 is not often observed
or imaged, probably because of
the close proximity to magnitude
2.7 iota Centauri. At
first sight it appears almost
featureless but there are subtle
dust lanes present.There is
active star formation going on
and NGC 5102 is an emission line
galaxy.
