Altair

al-TAIR

arabic: Al-Nasr al-Ṭāʾir (The Flying Eagle)

Definition

Altair is the brightest star in Aquila the Eagle and the twelfth-brightest star in the night sky (its formal name is Alpha Aquilae). It is a first-magnitude A-class main-sequence star, shining at about magnitude +0.77, and it spins so fast that its shape is visibly flattened. It lies roughly 16.7 light-years from Earth and currently projects onto the ecliptic at about 1°–2° tropical Aquarius, drifting slowly with precession.

In Tradition

Modern Western fixed-star practice — drawing on Robson (1923) and the Brady-Rosenberg revival — reads Altair as a star of bold action, swift advancement, and the courage to rise, though some sources also note a risk of impulsiveness or sudden reversal. The medieval Persian line carried by Masha'allah groups Altair with a cluster of fixed stars of Jupiter-Mars character; placed in the east of the chart or on the Midheaven, that cluster was thought to produce leadership of soldiers and a great-souled, visible presence.

In Practice

Fixed-star astrologers count Altair as active when it falls within roughly 1°–2° of your natal Sun, Moon, Ascendant, or Midheaven, or when a planet sits on its position along the zodiac. Some prefer the paran method (Brady) — checking whether Altair occupies one angle of the sky at the same moment a chart factor occupies another, as seen from the birthplace latitude. The star's position has to be adjusted for the chart's date, since it drifts with precession; modern ephemerides and fixed-star tables supply the date-corrected longitude. In observational work, you can refine further by checking for heliacal rising — first dawn visibility — at the birth latitude.

Historical Origin

The Arabic name Al-Nasr al-Ṭāʾir ("the flying eagle"), along with the Greek and Latin link to the eagle constellation Aquila, is attested in classical sources. Masha'allah's 8th-century *Book of Aristotle* III.1 (in the Persian Nativities corpus, Dykes 2008) places Altair within a five-star cluster of Jupiter-Mars character — with Regulus, Antares, Sirius, and Menkalinan — whose placement on the angles bears on the outcomes of a nativity. Vivian Robson's *The Fixed Stars and Constellations in Astrology* (1923, public domain) records the modern Western reading.
