NGC 2715 — SABc in Camelopardalis
SABc in Camelopardalis, 4.2 arcminutes across, its light 64 million years old. Measured by HyperLEDA, photographed by Pan-STARRS1. Recorded once.
About NGC 2715
What you are looking at
NGC 2715 is a late-type spiral: a small central bulge and open, loosely wound arms full of young stars and star-forming gas. A weak bar of stars crosses its centre. Its disc is steeply tilted, about 74° from face-on, so it appears as a long oval. From edge to edge its visible disc spans about 78,000 light-years (taking its redshift distance, which for a galaxy this near is approximate), about 80% of the Milky Way’s width.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as a member of a group of galaxies. One supernova has been recorded in it: SN 1987M. It is cited in 204 scientific papers indexed by SIMBAD, and recorded there under 17 different catalogue designations.
When this light set out
What a telescope records of NGC 2715 is light that left it about 64 million years ago; on Earth, an asteroid had ended the age of dinosaurs. The galaxy is moving away from us at about 1,329 km/s (3.0 million mph), carried by the expansion of the universe. For a galaxy this close, its own motion through space is a large share of that speed, so the distance worked out from it is approximate; distances measured from individual stars in it can differ.
Finding it in the sky
NGC 2715 lies in Camelopardalis. From most of the United States it never sets: it circles the north celestial pole all year, and stands highest on spring evenings, around March.
Its neighbours
At almost the same distance from us, and so its neighbours in space as well as on the sky: UGC 4701 (0.4° away on the sky, at least 410,000 light-years from it); UGC 4714 (0.5° away on the sky, at least 600,000 light-years from it); NGC 2655 (0.7° away on the sky, at least 730,000 light-years from it); NGC 2591 (1.6° away on the sky, at least 1,770,000 light-years from it), and 3 more.
By apparent size it is number 206 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 4.2 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.
