These are the Wikipedia:WikiProject Astronomy guidelines for ranking article importance. The rankings can be added to an astronomy-related article using the {{WPAstronomy}} template. See Category:Astronomy articles by importance and Category:Astronomy articles by quality for the current article rankings.

Importance scale[edit]

Articles that are given a WPAstronomy template are graded by importance based on their overall significance to the academic field of astronomy.

  • Fundamental astronomy topics are typically given a higher importance rating than secondary topics or minutiae.
  • Subjects that are the target of dedicated study by professional astronomers, as indicated by major observatory studies and scholarly journal articles, are generally of higher importance.
  • Widely known and famous topics in astronomy, as judged by the frequency of introductory publications and news stories, will also have a higher importance, as they are more likely to be the subject of encyclopedic searches.

Here are some general guidelines for the individual ratings:

  • Top: Fundamental and famous astronomy
  • High: Important or famous. Something an undergraduate astronomy major could have heard of or studied.
  • Mid: Cover articles that pretty much only people in the know heard about, while not being over-specialized.
  • Low: Everything else that has some significance to astronomy as a science, as well as amateur astronomy as a dedicated hobby.
  • Bottom: Not of importance to scientific astronomy overall, such as weekly local stargazing columns, recreational software, works of fiction or artistic interpretations. It also includes junk astronomy that matters to rational skepticism, but which is otherwise crank.
  • NA: Pages that are not in the article space, such a categories or projects.

These may vary somewhat depending on the subject category.

People[edit]

  • Top: People who made fundamental or very famous contributions to astronomy in general.
Examples: Albert Einstein, Galileo Galilei
  • High: People who made major or famous contributions within their field (usually, but not always, people with objects or effects named after them). All astronomers who won major prizes or awards besides the Nobel Prize. All astronomers who developed or invented widely used techniques or technologies within astronomy, or contributed to a significant body of scholarly publications.
Examples: Edwin Hubble, Subrahmanyan Chandrasekhar
  • Mid: Generally people who made important contributions to their fields who are recognized by their peers. Directors of major observatories or heads of space-based telescope projects. Well-published astronomers who satisfy the notability requirements.
Examples: Bernard Lyot, Heinrich Wilhelm Matthäus Olbers
  • Low: People who have made useful or interesting contributions, such as the discovery of a comet, asteroid, variable star or a nova. Notable amateurs. Popularizers of astronomy and heads of planetariums.
  • Bottom: Fringe theorists who have not been published in respected astronomical journals.

  • Mid: Classes of objects that have been the subject of individual scientific study beyond the basic properties.
Examples: Beta Lyrae variable, G-type main-sequence star, Supernova impostor, Yellow hypergiant.
  • Low: Minor sub-classes of objects that are variants of broader classes. Hypothetical objects that have a credible scientific basis.
Examples: Luminous red nova

Specific[edit]

Examples: Asteroid belt, Cygnus X-1, Hyades (star cluster), Jupiter, Local Group, Milky Way, Sun.
  • High: Readily observed or prototypical objects that have a large body of literature. This includes the major moons, dwarf planets, bright stars (1st magnitude or higher). Well known examples of primary types.
Examples: Andromeda galaxy, Ceres, Rigel.
  • Mid: Objects that have been the subject of scientific study beyond the basic orbital elements or classification. This includes minor moons, large asteroids, prominent stars (2nd & 3rd magnitude), well-studied extrasolar planets, widely-known astronomical features, nearby galaxies and unusual objects.
Examples: Proxima Centauri, IK Pegasi.
  • Low: Everything else, including most asteroids, stars, clusters and distant galaxies. These are objects that contribute little to the field and have few or no separate publications, but may be published as part of broader studies.
  • Bottom: Unconfirmed objects that were invented in fiction, UFOlogy, personal imagination, mysticism or mythology.

Discoveries[edit]

  • Top: Famous discoveries of major astronomical phenomena.
  • High: General history of astronomy; important discoveries that are not widely known.

Examples: Copernican Revolution, Egyptian astronomy, Zodiac
  • Low: Specialized topics important only within a culture.
Examples: Sothic cycle

Events[edit]

  • Top: Astronomical events that are widely important both within and outside of astronomy.
