Zeta Tucanae is located about 28.0 light-years from Sol. It lies in the central part of the constellation Tucana, the Toucan. Zeta Tucanae is a yellowish main sequence dwarf of spectral and luminosity type F8-G0 V, with about 98 percent of Sol's mass, 1.1 times its diameter, and 1.3 times its luminosity. The star may be only 44 to 79 percent as enriched as Sol with elements heavier than hydrogen ("metallicity"), based on its abundance of iron [1].
Spectroscopic analysis suggests that Zeta Tucanae may have an unseen companion.
A radial velocity study failed to detect a brown dwarf sized companion (with 20 to 80 times the mass of Jupiter) within 10 AUs of Zeta Tucanae[2]. The orbit of an Earth-like planet (with liquid water) around this star would be centered around 1.14 AU -- somewhat outside the orbital distance of Earth in the Solar System -- with an orbital period of about one and a quarter of an Earth year.
Locations in Zeta Tucanae
As of 2014, no Fen have visited Zeta Tucanae.
Some low-probability Fenspace Infinities timelines have the Stellvia Corporation stations Stellvia, Odyssey, and Wonderland relocating to the Zeta Tucanae system, leaving Ultima as a way-station in the Sol system. Higher-probability Fenspace Infinities timelines have Stellvia Corporation establishing an "advance base" in the Zeta Tucanae system in order to support astronomical research of Beta Hydri and its system.
