NGC 55

NGC 55 and the spiral galaxy NGC 300 have traditionally been identified as members of the Sculptor Group, a nearby group of galaxies in the constellation of the same name. However, recent distance measurements indicate that the two galaxies actually lie in the foreground.

It is likely that NGC 55 and NGC 300 form a gravitationally bound pair.

Burnham calls it "one of the outstanding galaxies of the southern heavens", somewhat resembling a smaller version of the Large Magellanic Cloud.

He mistook the galaxy's faint eastern section as a new find (even though John Herschel had drawn it) and that is how it got cataloged as IC 1537.{{Cite journal |last=Swift |first=L. |date=1898-09-01 |title=Catalogue No. 11 of Nebulae |url=https://ui.adsabs.harvard.edu/abs/1898AN....147..209S/abstract |journal=Astronomische Nachrichten |volume=147 |issue=13 |pages=209–220 |doi=10.1002/asna.18981471302 |bibcode=1898AN....147..209S |issn=0004-6337}}
