About NGC 4096
What you are looking at
NGC 4096 is a late-type spiral: a small central bulge and open, loosely wound arms full of young stars and star-forming gas. A weak bar of stars crosses its centre. Its disc is turned almost exactly side-on to us: the galaxy appears as a narrow blade of light, and its dust as a dark seam running along it. From edge to edge its visible disc spans about 45,000 light-years (taking its redshift distance, which for a galaxy this near is approximate), about half the width of the Milky Way.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as a member of a group of galaxies. Two supernovae have been recorded in it, the first in 1960; the most recent include SN 1960H, SN 2014bi. It is cited in 276 scientific papers indexed by SIMBAD, and recorded there under 16 different catalogue designations.
When this light set out
The light that reaches us from NGC 4096 today set out about 27 million years ago, when Antarctica had begun to freeze. The galaxy is moving away from us at about 564 km/s (1.3 million mph), carried by the expansion of the universe. For a galaxy this close, its own motion through space is a large share of that speed, so the distance worked out from it is approximate; distances measured from individual stars in it can differ.
Finding it in the sky
In the sky, NGC 4096 sits within the constellation Ursa Major. It is best placed on spring evenings: around 9:30 pm in April it stands about 83° high in the north, close to overhead, seen from the middle of the United States.
Its neighbours
At almost the same distance from us, and so its neighbours in space as well as on the sky: NGC 4144 (1.2° away on the sky, at least 580,000 light-years from it); NGC 4010 (1.3° away on the sky, at least 600,000 light-years from it); NGC 4218 (1.8° away on the sky, at least 830,000 light-years from it); NGC 4248 (2.0° away on the sky, at least 950,000 light-years from it), and 11 more.
By apparent size it is number 92 of the 12,657 galaxies on the Galaxy Origins register.

What is sold
A print of this galaxy and the record of the calculation, once. When it sells it leaves the register and is not offered again. We assign no names and no ownership — nobody can sell you those.
At 5.6 arcminutes this is a Exceptional galaxy, which is the tier where a real photograph shows clear structure and dust lanes. The tier comes from the measured diameter, not from a price list.
