Tucana is not an area of sky filled with bright stars, though Alpha Tucanae reaches a magnitude of +2.9. More important, though, are Tucana's stock of extragalactic objects, including not only the bright Globular Cluster 47 Tucanae, but also the Small Magellanic Cloud.
Stars In Tucana
47 Tucanae (NGC 104)
Astronomers using the Hubble telescope made the first broad search for planets far beyond our local stellar neighborhood. They trained Hubble's "eagle eye" for eight days on a swarm of 35,000 stars in 47 Tucanae, located in the southern constellation Tucana. The researchers expected to find 17 "extrasolar" planets. To their surprise, they found none. These results may be the first evidence that conditions for planet formation and evolution are different in other regions of our Milky Way Galaxy.
Star-Forming Nebula in the SMC In Tucana
SMC N81
This view of a newborn star cluster within the Small Magellanic Cloud reveals young, brilliant stars cradled within the nebula known as N81. The two most luminous stars, seen in this Hubble Space Telescope image as a very close pair near the center of N81, emit copious ultraviolet radiation, causing the nebula to glow through fluorescence.
Planetary Destination In Tucana
HD 4308 (G5 V)
Parent Star: HD 4308 (G5 V) in the constellation of Tucana is located at a distance of 21.9 pc from our Solar system Co-ordinates of Right Ascension: 00 44 39 & Declination: -65 38 58. The apparent magnitude of the star is V=6.54. The habitability zone is unknown. Orbiting around HD 4308 is planet HD 4308 b the planet is believed to be a brown dwarf planet and its exitence has been confirmed. The Planets Appearance is a brown haze.
