Zeta Telescopii (ζ Telescopii) is the second-brightest star in the southern constellation of Telescopium. It is a solitary,[7] orange-hued star that is visible to the naked eye with an apparent visual magnitude of +4.13.[2] Based upon an annual parallax shift of 26.7 mas as seen from Earth,[1] it is located around 122 light years from the Sun.

This is a red clump[2] giant star of spectral type K1 III-IV.[3] It is just 40% more massive than the Sun, but has a radius eight times larger and shines with about 30 times its luminosity. The surface of Zeta Telescopii has an effective temperature of 4,824 K,[8] giving it the orange hue typical of K-type stars.[9]
