Zeta Tucanae

Zeta Tucanae (ζ Tuc, ζ Tucanae) is a a spectral class F9.5 main sequence star. The composition and mass of this star indicate an estimated age of three billion years.

Based upon an excess emission of infrared radiation at 70 micrometres, this system is believed to have a debris disk. The disk is orbiting the star at a minimum radius of 2.3 astronomical units. It is radiating with a maximum temperature of 218 K.

The components of this star's space velocity are U = −60, V = −4 and W = −38 km/s. These correspond to the velocity toward the galactic center, the velocity along the direction of galactic rotation, and the velocity toward the north galactic pole, respectively. It is orbiting through the galaxy at a mean distance of 8.4 kpc from the galactic center and with an orbital eccentricity of 0.16.
