Star in the constellation Capricornus
Kappa Capricorni (κ Cap, κ Capricorni) is a solitary[9] star in the constellation Capricornus. It is visible to the naked eye with an apparent visual magnitude of +4.73.[2] Based upon an annual parallax shift of 11.09 mas as seen from the Earth,[1] the star is located about 294 light years from the Sun.
This is a yellow-hued, evolved, G-type giant star with a stellar classification of G8 III.[3] There is a 91% probability that it is currently on the horizontal branch, rather than the red giant branch.[6] As such, it is a red clump[10] giant with an estimated 2.43 times the mass of the Sun and has expanded to 13.28 times the radius of the Sun.[6] The star is about 1.2[7] billion years old and has a projected rotational velocity that is too small to be measured.[4] It radiates 107 times the solar luminosity from its photosphere at an effective temperature of 5,096 K.[6]
