NGC 2770
spiral galaxy in the constellation Lynx
NGC 2770 is a spiral galaxy in the northern constellation of Lynx, near the northern constellation border with Cancer. It was discovered by German-born astronomer William Herschel on December 7, 1785. J. L. E. Dreyer described it as, "faint, large, much extended 150°, mottled but not resolved, 2 stars to north". NGC 2770 was the target for the first binocular image produced by the Large Binocular Telescope.
The morphological classification of SBc indicates a barred spiral with moderately-wound arms. The physical properties of this galaxy are similar to those of the Milky Way. The combined mass of stars in the galaxy is estimated at 2.1×1010 M☉, and it has a star formation rate of ~1.1 M☉ y−1. There are no apparent perturbations of the galaxy due to suspected interaction with the companion galaxy, NGC 2770B.
Supernovae
Four supernovae have been observed in NGC 2770 within a twenty years span. This high rate is considered anomalous for an ordinary galaxy. The explanation may lie in a recently enhanced star formation rate due to interaction with a companion galaxy.
This brief starts where responsible research should: with the source description of “NGC 2770” as spiral galaxy in the constellation Lynx. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as spiral galaxy in the constellation Lynx. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q817161. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1785 and 1010.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
