Lambda2 Sculptoris is an orange-hued star in the southern constellation of Sculptor. On dark nights it is faintly visible to the naked eye, having an apparent visual magnitude of +5.90.[2] Based upon an annual parallax shift of 9.63 mas as measured from Earth, it is located at a distance of 331 light-years.[1] It has a relatively large proper motion, advancing Template:Val per year across the sky.[1]
The spectrum of this star matches a spectral class of K1III,[4] with the luminosity class III indicating it is a giant star that has exhausted the hydrogen at its core. It is now fusing helium, being in the evolutionary stage known as the horizontal branch.[3] Estimates of its mass and age give two different values: 1.12 or 1.26 solar masses and 4.64 or 6.50 billion years.[3] It has expanded to 12.01 times the Sun's radius and radiates 56.7 times the solar luminosity from its photosphere at an effective temperature of Template:Val.[6]
