About NGC 5377
What you are looking at
NGC 5377 is an early-type spiral: a large, bright central bulge wrapped in smooth, tightly wound arms. Its disc is steeply tilted, about 77° from face-on, so it appears as a long oval. From edge to edge its visible disc spans about 91,000 light-years, close to the width of the Milky Way.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as a galaxy with an active nucleus, powered by its central black hole. One supernova has been recorded in it: SN 1992H. It is cited in 247 scientific papers indexed by SIMBAD, and recorded there under 20 different catalogue designations.
When this light set out
The light that reaches us from NGC 5377 today set out about 86 million years ago, when dinosaurs were at their peak. The galaxy is moving away from us at about 1,796 km/s (4.0 million mph), carried by the expansion of the universe.
Finding it in the sky
In the sky, NGC 5377 sits within the constellation Canes Venatici. It is best placed on spring evenings: around 9:30 pm in May 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: UGC 8876 (1.3° away on the sky, at least 1,900,000 light-years from it); NGC 5439 (1.3° away on the sky, at least 2,010,000 light-years from it); NGC 5425 (1.4° away on the sky, at least 2,140,000 light-years from it); NGC 5301 (2.0° away on the sky, at least 3,050,000 light-years from it), and 4 more.
By apparent size it is number 304 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 3.6 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.
