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, [1] it is located roughly 340 light-years from the Sun. It has a relatively large proper motion, advancing 0.284±0.015 arcsecond per year across the sky. [8]
At an age of about 3.58 [4] billion years, Lambda2 Sculptoris is an evolved red-clump [9] giant star with a stellar classification of K0 III. [3] It is presently on the horizontal branch and is generating energy through the nuclear fusion of helium at its core. The star has an estimated 1.49 [4] times the mass of the Sun and has expanded to about 14 [6] times the Sun's radius. It is radiating 63 [4] times the solar luminosity from its photosphere at an effective temperature of 4,531 K. [4]
