NGC
488
is a face-on spiral galaxy in the constellation Pisces. It
is at a distance of about 90 million light-years away from
Earth. Its diameter is estimated to be 52,6 Kpc (171.000
ly). The galaxy has a large central bulge, and is considered
a prototype galaxy with multiple spiral arms. Its arms are
tightly wound. Star forming activity has been traced within
the arms. The nucleus of NGC 488 has been found to be
chemically decoupled, being twice as metal rich as the
central bulge of the galaxy. NGC 488, with the exception of
its smaller companions, that form NGC 488 group, is an
isolated galaxy. (wiki)
