The table lists the 172 visually brightest stars of the sky, those
through visual magnitude 3.00 (that is, all the stars of the minus
first, zeroth, first, and second magnitudes as seen with the naked
eye, and extended to mid-third), adapted originally from the
Cambridge Encyclopedia of Stars (J. B. Kaler, Cambridge
University Press, 2006). Most data are taken from the Bright Star
Catalogue (BSC, Fourth Revised Edition, D. Hoffleit and C.
Jaschek, Yale University Observatory, New Haven, 1982) and SIMBAD .
With some exceptions, distances are taken from the Hipparcos Catalogue, as are proper motions (motions across
the line of sight). Distances of first magnitude (and brighter)
stars are from the second reduction, as are some others as indicated
in the stars' descriptions.
Magnitudes (hence rankings), colors (to determine the degree of interstellar dust absorption), and
spectral classes are those of the BSC. In cases of ties in
magnitudes, the stars are ranked from hottest to coolest. Many of
the stars are binary (double)
or even more complex. Close doubles are noted, wide ones ignored.
Doubles unresolvable with the naked eye (ignoring faint companions)
are ranked according to the combined magnitudes, with data on
individuals given in the remarks. Note that listings such as this
one cannot be unique and definitive because of stellar variability,
different sources of data (which can give slightly different
magnitudes), and different ways of treating binaries.
Several stars present special cases. The individual members of the
Rigil Kentaurus (Alpha Centauri,
ignoring Proxima), Capella (Alpha
Aurigae), Hadar (Beta Centauri), and Acrux (Alpha Crucis) pairs would each make the
list on their own. As a result, the table actually contains the 174
visually brightest stars. Castor A
(which is itself double), at magnitude 1.93, would make the list as
well, ranking 43rd, as would the brighter components of Spica, Mizar, Almach (Gamma And), Muhlifain (Gamma Cen), Algieba (Gamma Leo), and Graffias (Beta Sco). Because they are
easily separable, the components of Rigil Kentaurus and Acrux are
presented as individuals, though each is given the rank as if they
were combined. Betelgeuse and Antares are variables that will change
their brightness ranks. Outbursting Dschubba (Delta Scorpii) and Gamma Cassiopeiae are listed according to
their catalogued magnitudes. Scheat
(Beta Peg) can drop to third magnitude.
Statistics: Ignoring binaries, there are two stars of the minus first
magnitude (brighter than -0.50, Canopus
and Sirius), 8 of zeroth magnitude
(between -0.49 and +0.50), 13 of first magnitude (between 0.51 and
1.50), and 70 of second magnitude (between 1.51 and 2.50). The
number increases very rapidly with decreasing brightness, over 200
in third magnitude, and so on.
