Nomenclature

δ Corvi (Latinised to Delta Corvi) is the star's Bayer designation, which is abbreviated Delta Crv or δ Crv.

It bore the traditional name Algorab derived from Arabic الغراب al-ghuraab, meaning 'the crow'. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included Algorab for this star.

In Chinese, 軫宿 (Zhěn Sù), meaning Chariot, refers to an asterism consisting of Delta Corvi, Gamma Corvi, Epsilon Corvi and Beta Corvi. Consequently, Delta Corvi itself is known as 軫宿三 (Zhěn Sù sān, English: the Third Star of Chariot).

Editorial analysis

Why this record matters

The phrase “binary star in the southern constellation Corvus” 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.

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 Jul 28, 2026. The linked authority identifier is Q15698. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2016.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
