Zeta Tuc is also known as HR 77, Gl 17, and HD 1581. Nearby star system. It is a nearby yellowish star with a late F or early G spectrum. It may have an unseen spectroscopic binary partner. It is slightly less massive, slightly larger, and slightly brighter than the Sun and only 44 to 79% its metalicity. It is one of the least variable stars observed during the Hipparcos mission. Its similarity to the Sun make it an interesting target. It is about 3 Billion Years old. It is thought to have a debris disk. Its rotational velocity appears to be almost zero, indicating it presents its pole towards us, which would make finding planets through radial velocity nearly impossible.
