Tucana

Tucana is a constellation of stars in the southern sky, created in the late sixteenth century. Its name is Latin for the toucan, a South American bird. This is not a prominent constellation as all of its stars are third magnitude or fainter; the brightest is Alpha Tucanae at apparent visual magnitude 2.87.

The recommended three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is 'Tuc'. The official constellation boundaries, as set by Eugène Delporte in 1930, are defined by a polygon of 10 segments. In the equatorial coordinate system, the right ascension coordinates of these borders lie between 22h 08.45m and 01h 24.82m, while the declination coordinates are between –56.31° and -75.35°.
