NGC 4328
galaxy
NGC 4328 is a nucleated dwarf elliptical or lenticular galaxy located about 48 million light-years away based on observations by the Hubble Space Telescope using the TRGB distance indicator. NGC 4328 was discovered on March 21, 1784 by astronomer William Herschel and is a member of the Virgo Cluster in the "A'' subgroup. On the sky, NGC 4328 is located in the constellation Coma Berenices.
NGC 4328 is a companion of Messier 100, along with NGC 4323 and lies 78,000 light-years (24 kiloparsecs) from Messier 100. A possible passage of NGC 4328 close to Messier 100, may explain the lopsidedness in the southwestern portion of Messier 100. However, there are no strong signs of interactions in the H I distribution of Messier 100 which may be due to an interaction between the two galaxies. Despite this, recent observations are too shallow to detect tidal streams in the H I distribution of Messier 100 caused by a possible interaction between the two galaxies.
NGC 4328 is host to a supermassive black hole with an estimated mass of 6.1×106 solar masses.
Begin with the source’s own compact description: “NGC 4328” is galaxy. The dossier treats that line as a proposition to test through galaxy, not as a finished interpretation.
Why this record matters
The phrase “galaxy” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q1110745. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1784.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
