Tucana has a delta-Scuti type variable and a pulsating variable (Lb), neither one of which is of much interest to the amateur observer. Theta Tucanae is a delta Scuti type variable with a range of 6.06 to 6.15, and period of one hour 11 minutes.

Tucana, the toucan:
A modern constellation created in 1603 by the astronomer Johann Bayer. The constellation has no classical mythology, it was created to honor the colorful tropical bird encountered by European sailors.

47 Tucanae (NGC 104)
Hubble image of stars near the center of 47 Tuc
The second brightest globular cluster in the sky, after Omega Centauri. To the unaided eye it looks like a misty star.

Tucana's brightest star is of only third magnitude, but the constellation is distinguished by two features: firstly, the globular star cluster 47 Tucanae, rated the second-best such object in the entire sky, ...

Bright globular clusters include Omega Centauri, 47 Tucanae, and M13. In the Milky Way, all globular clusters are old. Most are members of the Galactic halo, and the rest are members of the thick disk. [C95] ...

The Small Cloud (SMC) is almost completely in the constellation Tucana, and measures approx. 4° in diameter. Both are nearly 160,000 light-years from the earth.

After all, 47 Tucanae is just one globular. But all the Milky Way's globulars were born about 13 billion years ago, when the galaxy was just forming, and the infant galaxy didn't possess many of the heavy elements thought necessary to form planets.

The Milky Way's satellite system consists of Sag DEG, Large Magellanic Cloud, Small Magellanic Cloud, Canis Major Dwarf, Ursa Minor Dwarf, Draco Dwarf, Carina Dwarf, Sextans Dwarf, Sculptor Dwarf, Fornax Dwarf, Leo I, Leo II, Tucana Dwarf, ...

The globular star cluster 47 Tucanae, which is made up of about 1 million stars, is one of the densest globular clusters in the Southern Hemisphere.

Small Magellanic Cloud (SMC) Satellite galaxy to our own Milky Way system, appearing to the unaided eye as a nebulous patch in the constellation of Tucana. From mid-southern latitudes the SMC is circumpolar.

They are both bright (12 magnitude) compact open clusters located in the Small Magellanic Cloud spanning a distance of 65 light years across and located 200,000 light years in distance from the Blue Planet in the Constellation Tucana.

The Small Magellanic Cloud (SMC) is an irregular-shaped galaxy in the Local Group. The irregular shape may be the result of a disturbance, perhaps a collision of two galaxies. The Small Magellanic Cloud (SMC) is near the constellation Tucana, ...

The Large Magellanic Cloud (LMC) is near the constellation Dorado, and is 163,000 light-years away. The Small Magellanic Cloud (SMC) is near the constellation Tucana, and is under 200,000 light-years away.

M13 is the most spectacular globular cluster for northern observers - only w Centauri and 47 Tucanae in southern skies outshine it. It is noticable with an unaided eye about 2°30' S of h Herculi (see finder chart below).
