About NGC 6674
What you are looking at
NGC 6674 is a spiral with a sizeable central bulge and well-defined arms, close in type to the Milky Way. Its disc is steeply tilted, about 63° from face-on, so it appears as a long oval. From edge to edge its visible disc spans about 190,000 light-years, about 1.9 times the width of the Milky Way.
What astronomers have recorded
It is cited in 122 scientific papers indexed by SIMBAD, and recorded there under 14 different catalogue designations.
When this light set out
The light that reaches us from NGC 6674 today set out about 164 million years ago, when Pangaea had begun to break apart. The galaxy is moving away from us at about 3,429 km/s (7.7 million mph), carried by the expansion of the universe.
Finding it in the sky
NGC 6674 lies in Hercules. It is best placed on summer evenings: around 9:30 pm in August it stands about 75° high in the south, 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 6671 (1.1° away on the sky, at least 3,050,000 light-years from it); UGC 11307 (2.4° away on the sky, at least 6,890,000 light-years from it).
By apparent size it is number 238 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 4.0 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.
