NGC 361
open cluster

NGC 361 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on September 6, 1826, by James Dunlop. It was described by Dreyer as "very very faint, pretty large, very little extended, very gradually brighter middle." At an aperture of 31.0 arcseconds, its apparent V-band magnitude is 12.24, but at this wavelength, it has 0.40 magnitudes of interstellar extinction.
NGC 361 is about 8.1 billion years old. Its estimated mass is 2.15×105 M☉, and its total luminosity is 1.04×105 L☉, leading to a mass-to-luminosity ratio of 2.07 M☉/L☉. All else equal, older star clusters have higher mass-to-luminosity ratios; that is, they have lower luminosities for the same mass.
The public source identifies “NGC 361” as open cluster. This brief keeps that definition visible, then builds a research path around cluster.
Why this record matters
A short description can identify a subject without explaining its stakes. For “NGC 361”, the useful work is to connect “open cluster” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q1036271. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1826.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
How to read it
