Tucana Constellation Star Map

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. Tucana is the 48th largest in terms of size in the night sky.

The constellation 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.

There are 6 stars that make up the main constellation. The hipparcos satellite scanned and detailed 930 stars. There are 27 stars that can be seen with the naked eye in the constellation on a very clear night sky.

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.

There are 14 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. There is a dedicated page for exoplanets in Tucana. The current largest star so far identified in the constellation of Tucana is HV 11423.

There are no deep space objects that were identified by Charles Messier in this constellation. There are 1 non-Messier deep space objects that are covered on this site and the list is below.

Tucana Star Facts

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.

HIP 5496, Tucana's Nearest Star

The nearest star to Earth is HIP 5496 which is roughly about 26.73 Light Years from the Earth. The nearest star to the Earth with an exoplanet is HD 4308 which is about 71.94 Light Years.

HIP 115973, Tucana's Furthest Star

The furthest star that is located in the constellation is HIP 115973 and it is 326163.3 light years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.

Alpha Tucanae, Brightest Star in Tucana

The brightest star in Tucana is Alpha Tucanae and is located about 53.26 light years from the Sun. The star has a apparent magnitude of 2.87 but an absolute magnitude of -1.07 when the star is viewed from a distance of 10 Parsecs or 32.6 Light Years. The star is recognised as being the brightest in the constellation as it has the Bayer status of Alpha.

HD 4088, Tucana's Dimmest Visible Star

The dimmest star that can be seen in Tucana with the naked eye is HD 4088. The dim star has an apparent magnitude of 5.99. The dimmest star that a person is able to see with their naked eye is 6.0 magnitude based on the table in the reference. Ref: University of Michigan.

Tucana Mythology

There is no Greek Legend behind this constellation. It was created by Pieter Dirkszoon Keyser and Frederick de Houtman to fill in the voids in the astronomical charts. The Toucan at the time seemed a worthy animal to name a constellation after.
