Source-derived summary

NGC 492, also occasionally referred to as PGC 4976 or GC 280, is a barred spiral galaxy in the constellation Pisces. It is located approximately 590 million light-years from Earth and was discovered on December 6, 1850 by Irish engineer Bindon Blood Stoney. Although John Dreyer, creator of the New General Catalogue, credits the discovery to astronomer William Parsons, 3rd Earl of Rosse, he notes that many of his claimed discoveries were made by one of his assistants. In the case of NGC 492, the discovery was made by Bindon Stoney, who discovered it along with NGC 486, NGC 490 and NGC 500 during his observation of NGC 488 using Lord Rosse's 72" telescope.

The object was initially described by Stoney as "extremely faint, small, round, 25" diameter, low surface brightness, no concentration". The position noted was "on line with a mag 12 star 3.7' NW and a faint pair of mag 14-14.5 stars 2' NW".

Editorial summary

This brief starts where responsible research should: with the source description of “NGC 492” as galaxy. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1850—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where galaxy can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as galaxy. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

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 3, 2026. The linked authority identifier is Q1036945. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1850.

Critical limits

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

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
