About NGC 5297
What you are looking at
NGC 5297 is a late-type spiral: a small central bulge and open, loosely wound arms full of young stars and star-forming gas. 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 124,000 light-years, about 1.3 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. It is cited in 185 scientific papers indexed by SIMBAD, and recorded there under 16 different catalogue designations.
When this light set out
What a telescope records of NGC 5297 is light that left it about 115 million years ago; on Earth, the first flowering plants had appeared. The galaxy is moving away from us at about 2,406 km/s (5.4 million mph), carried by the expansion of the universe.
Finding it in the sky
In the sky, NGC 5297 sits within the constellation Canes Venatici. It is best placed on spring evenings: around 9:30 pm in May it stands about 86° 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 8733 (0.6° away on the sky, at least 1,230,000 light-years from it); NGC 5336 (1.2° away on the sky, at least 2,450,000 light-years from it); NGC 5290 (2.2° away on the sky, at least 4,350,000 light-years from it); NGC 5289 (2.4° away on the sky, at least 4,770,000 light-years from it), and 7 more.
By apparent size it is number 288 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 3.7 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.
