μ Sculptoris, Latinized as Mu Sculptoris, is a solitary, [11] orange-hued star in the southern constellation of Sculptor. It is visible to the naked eye as a dim point of light with an apparent visual magnitude of +5.30. [2] This star is located approximately 291 light years from the Sun based on parallax, [7] and it is drifting further away with a radial velocity of +16 km/s. [1]
This object is an aging K-type giant star with a stellar classification of K1 III. [4] Having exhausted the supply of hydrogen at its core, this star expanded and cooled off the main sequence. At present it has 11 [1] times the girth of the Sun. It is a suspected variable star of unknown type, with its brightness measured as varying from magnitude 5.30 down to 5.33. [3] The star has 1.32 [8] times the mass of the Sun and is radiating 61 [1] times the Sun's luminosity from its swollen photosphere at an effective temperature of 4899 K. [1]
