About NGC 1353
What you are looking at
NGC 1353 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 71° from face-on, so it appears as a long oval. From edge to edge its visible disc spans about 77,000 light-years, about 79% of the Milky Way’s width.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as an emission-line galaxy: its spectrum shows the glow of gas lit by young stars. It is cited in 135 scientific papers indexed by SIMBAD, and recorded there under 16 different catalogue designations.
When this light set out
Its light has been travelling for about 73 million years. When it left, dinosaurs were at their peak. The galaxy is moving away from us at about 1,530 km/s (3.4 million mph), carried by the expansion of the universe.
Finding it in the sky
NGC 1353 lies in Eridanus. It is best placed on winter evenings: around 9:30 pm in December it stands about 29° 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: IC 1953 (0.8° away on the sky, at least 980,000 light-years from it); IC 1962 (1.0° away on the sky, at least 1,230,000 light-years from it); NGC 1377 (1.1° away on the sky, at least 1,380,000 light-years from it); NGC 1332 (1.4° away on the sky, at least 1,840,000 light-years from it), and 10 more.
By apparent size it is number 311 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.
