List of proper names of stars

List of proper names of stars is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of proper names of stars rather than just read about it. In short: These names of stars that have either been approved by the International Astronomical Union or which have been in somewhat recent use. IAU approval comes mostly from its Working Group on Star Names, which has been publishing a "List of IAU-approved Star Names" since 2016.

Key takeaways

  • List of proper names of stars belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect List of proper names of stars to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of List of proper names of stars from memory before moving on to harder problems.

Reference excerpt

These names of stars that have either been approved by the International Astronomical Union or which have been in somewhat recent use. IAU approval comes mostly from its Working Group on Star Names, which has been publishing a "List of IAU-approved Star Names" since 2016. As of August 2026, the list included a total of 626 proper names of stars.

Background Of the roughly 10,000 stars visible to the naked eye, only a few hundred have been given proper names in the history of astronomy. Traditional astronomy tends to group stars into constellations or asterisms and give proper names to those, not to individual stars. Many star names are, in origin, descriptive of the part in the constellation they are found in; thus Phecda, a corruption of Arabic فخذ الدب (fakhdh ad-dubb, 'thigh of the bear'). Only a handful of the brightest stars have individual proper names not depending on their asterism; so Sirius ('the scorcher'), Antares ('rival of Ares', i.e., red-hued like Mars), Canopus (of uncertain origin), Alphard ('the solitary one'), Regulus ('kinglet'); and arguably Aldebaran ('the follower' [of the Pleiades]) and Procyon ('preceding the dog' [Sirius]). The same holds for Chinese star names, where most stars are enumerated within their asterisms, with a handful of exceptions such as 織女 ('weaving girl') (Vega). In addition to the limited number of traditional star names, there were some coined in modern times, e.g. "Avior" for Epsilon Carinae (1930), and a number of stars named after people (mostly in the 20th century).

IAU catalog

In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee Working Group on the Public Naming of Planets and Planetary Satellites during the 2015 NameExoWorlds campaign and recognized by the WGSN. Further batches of names were approved on 21 August, 12 September, 5 October, and 6 November 2016. These were listed in a table of 102 stars included in the WGSN's second bulletin, dated November 2016. The next additions were done on 1 February 2017 (13 new star names), 30 June 2017 (29), 5 September 2017 (41), 17 November 2017 (3), 1 June 2018 (17), and on 10 August 2018 (6). All 336 names are included in the current List of IAU-approved Star Names. In 2019, the IAU organised its IAU 100 NameExoWorlds campaign to name exoplanets and their host stars. The approved names of 112 exoplanets and their host stars were published on 17 December 2019, with an additional pair of names (for the star HAT-P-21 and its planet) approved on 1 March 2020. An additional two star names were approved on 4 April 2022. In June 2023, an additional 20 names were approved in the NameExoWorlds 2022 campaign, bringing the total to 471 named stars. Since 2024, newly approved names have appeared on the exopla.net website maintained by the WGSN. 19 names were approved in 2024, and 40 in 2025. As of August 2026, 96 additional star names have been approved, bringing the total to 626.

List In the table below, unless indicated by a "†", the "modern proper name" is the name approved by the WGSN and entered in the List of IAU-approved Star Names or otherwise approved by the IAU. The WGSN decided to attribute proper names to individual stars rather than entire multiple-star systems. Names marked with a "†" have not been approved by the IAU. For such names relating to members of multiple-star systems, and where a component letter (from, e.g., the Washington Double Star Catalog) is not explicitly listed, the WGSN says that the name should be understood to be attributed to the visually brightest component. In the "Historical names/comments" column, "NameExoWorlds [year]" denotes that the name was approved by the IAU as a consequence of that year's NameExoWorlds campaign.

Worked examples

Example 1 — a first encounter with List of proper names of stars

Start with the simplest possible case. Write down what List of proper names of stars claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of proper names of stars before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of proper names of stars ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of proper names of stars

In research
List of proper names of stars appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses List of proper names of stars in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
List of proper names of stars is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of names, Lists of stars, Stars with proper names, so understanding it makes those chapters shorter.
In everyday life
Look for List of proper names of stars outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
