About NGC 210
What you are looking at
NGC 210 is a spiral with a sizeable central bulge and well-defined arms, close in type to the Milky Way. A weak bar of stars crosses its centre. It is tilted about 55° to our line of sight, enough to show both the shape of its arms and the depth of its disc. From edge to edge its visible disc spans about 113,000 light-years, about 1.2 times the width of the Milky Way.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as one of a pair of galaxies. One supernova has been recorded in it: SN 1954R. It is cited in 183 scientific papers indexed by SIMBAD, and recorded there under 17 different catalogue designations.
When this light set out
Its light has been travelling for about 79 million years. When it left, dinosaurs were at their peak. The galaxy is moving away from us at about 1,637 km/s (3.7 million mph), carried by the expansion of the universe.
Finding it in the sky
In the sky, NGC 210 sits within the constellation Cetus. It is best placed on autumn evenings: around 9:30 pm in November it stands about 36° 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 178 (0.5° away on the sky, at least 630,000 light-years from it); IC 51 (1.5° away on the sky, at least 2,020,000 light-years from it); NGC 255 (3.0° away on the sky, at least 4,070,000 light-years from it).
By apparent size it is number 127 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 5.0 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.
