Tucana is a constellation of stars in the southern sky, named after the
toucan, a South American bird. It is one of twelve constellations
conceived in the late sixteenth century by Petrus Plancius from the
observations of Pieter Dirkszoon Keyser and Frederick de Houtman. It
first appeared on a 1598 celestial globe by Plancius and Jodocus Hondius
in Amsterdam and was depicted in Johann Bayer's star atlas Uranometria
of 1603. French explorer and astronomer Nicolas Louis de Lacaille gave
its stars Bayer designations in 1756. Tucana is not a prominent
constellation as all of its stars are third magnitude or fainter; the
brightest is Alpha Tucanae with an apparent visual magnitude of 2.87.
Beta Tucanae is a star system with six member stars, while Kappa is a
quadruple system. Five star systems have been found to have exoplanets
to date. The constellation contains most of the Small Magellanic Cloud,
along with 47 Tucanae (pictured), one of the brightest globular clusters
in the sky. The constellations Tucana, Grus, Phoenix and Pavo are
collectively known as the "Southern Birds".
