Kappa Telescopii (κ Telescopii) is a solitary, [8] yellow-hued star in the southern constellation of Telescopium. With an apparent visual magnitude of +5.20, [2] it is visible to the naked eye. Based upon an annual parallax shift of 12.00 mas as seen from Earth, [1] it is located around 272 light years from the Sun.
At the age of around 1.25 billion years, [6] this an evolved giant star with a stellar classification of G8/K0 III, [3] showing a spectrum with characteristics intermediate between a G-type and a K-type star. It has an estimated 1.9 times the mass of the Sun and 10.5 times the Sun's radius. [6] The star is radiating 77.6 times the solar luminosity from its photosphere at an effective temperature of 4,968 K. [6] It is unclear whether it is cooling or heating up on its evolutionary pathway through the red clump. [5]
