Tucana, The Toucan Constellation

Tucana (Pronounciation:Two-can-a, Abbrev:Tuc, Latin:Tucanae) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Tucana takes up 294.557 sq. degrees of the night sky which equates to 0.71% of the night sky. The constellation gets its name as it name means The Toucan . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by Pieter Dirkszoon Keyser and Frederick de Houtman years later.

Tucana is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Tucana is a southern hemispheric constellation which means it can't be seen easily or at all from the northern hemisphere.

The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
