This spiral galaxy is located in the
direction of Coma Berenices. A type II supernova went off in
this galaxy some time ago (SN 1941a). Several papers estimate
its appearent magnitude was 13 and absolute magnitude to be
around 15.7. Astronomers estimate this galaxy to be about 29
million light years away. Like many nearby spiral galaxies, NGC
4559 displays bright star-forming regions and dust lanes in its
expansive arms. There are also a number of background galaxies
and galaxy groups in this area.
