Star in the constellation Sculptor
ι Sculptoris ,
Latinized as Iota Sculptoris and abbreviated iot Scl, is a solitary
[11]
star in the southern
constellation of
Sculptor . It is visible to the naked eye as a dim, orange-hued point of light with an
apparent visual magnitude of 5.18.
[2] The star is located approximately 336
light years from the Sun based on
parallax ,
[1] and is drifting further away with a
radial velocity of +21 km/s.
[6]
This is an aging
giant star with a
stellar classification of K0III,
[3] currently on the
red giant branch .
[7] It has 2.9 times the
mass of the Sun and has expanded to 12 times the
Sun's radius . The star is radiating 97 times the
luminosity of the Sun from its enlarged
photosphere at an
effective temperature of 5,020 K.
[7] These coordinates are a source for
X-ray emission , which is most likely (99.4% chance) coming from the star.
