[2] Based upon an annual parallax shift of 43.37 mas as seen from Earth,[1] this star is located about 75 light years from the Sun.

[4] Gray et al. (2006) has it classed as F4 V, which would match an ordinary F-type main-sequence star.

At the age of around 1.4[10] billion years, it retains a relatively high rate of spin with a projected rotational velocity of 94 km/s.

[11] It is radiating 11[8] times the Sun's luminosity from its photosphere at an effective temperature of 6,679 K.[10] Gamma Tucanae may (95% chance) have a distant co-moving companion – a magnitude 6.64 G-type main-sequence star of class G0 V designated HD 223913.

This object has the same mass as the Sun and is separated from Gamma Tucanae by about 11 ly (3.5 pc).
