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.
As of 2014, no Fen have visited Zeta Tucanae.

The First Zeta Tucanae Exploration Mission
Funded by Stellvia Corporation and carried out by the Artemis Foundation, the first Zeta Tucanae exploration mission took place from mid-November 2015 to mid-April 2016.
The members of this exploration team were carefully chosen by the Artemis Foundation with an eye toward ensuring they won't be at each others' throats midway through the mission. With a minimum of three months away from Sol (one month to reach Zeta Tucanae, at least one month exploring, one month to return), the crew needed to be able to get along with each other.
Fleet
Two ships took part in this system survey.
Calypso was the main ship of the survey. This was the first mission for the Shuttle, not counting her shakedown cruise in early-November 2015. Her cargo bay was loaded with a large optical telescope and a number of non-AI probes and communication relays; of these, only the telescope was brought back to Sol.
Takumi F. was the survey's support ship. This Roadrunner-class supply ship usually runs produce from Wonderland to Genaros and "previously-enjoyed produce" back to Wonderland; this was the ship's first long-term mission. Six of the ship's eight cargo containers were stocked with non-perishable foods; one was a vehicle bay holding a waved Ford pickup truck, basic mechanic's tools, and some spare parts; the other container was outfitted as a recreation room, with a collar and tube for Calypso to dock.

Known Places Around 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 and point-of-presence in the Sol system. Higher-probability Fenspace Infinities timelines have Stellvia Corporation funding the establishment of an Artemis Foundation "advance base" in the Zeta Tucanae system in order to support astronomical research of Beta Hydri, Gamma Pavonis, and their systems.
