36 Capricorni is a single,[8] yellow-hued star in the southern constellation of Capricornus. It is visible to the naked eye with an apparent visual magnitude of +4.50.[2] The distance to this star, as determined from an annual parallax shift of Script error: No such module "val".,[1] is around 171 light years. It is currently moving closer with a heliocentric radial velocity of −21 km/s, and will come within Script error: No such module "convert". in about 685,000 years ago.[5]
This is an evolved G-type giant star with a stellar classification of G7IIIb Fe–1,[4] where the suffix notation indicates an underabundance of iron found in the spectrum. At the age of 770 million years it has become a red clump giant, meaning it is generating energy through helium fusion at its core. It has 2.26 times the mass of the Sun, but has expanded to 8.6 times its radius. It is radiating 43 times the Sun's luminosity from its photosphere at an effective temperature of 5,047 K.[3]
Chinese name
In Chinese, Script error: No such module "Lang". (Script error: No such module "Lang".), meaning Twelve States, refers to an asterism which is represent twelve ancient states in the Spring and Autumn period and the Warring States period, consisting of 36 Capricorni, φ Capricorni, ι Capricorni, 37 Capricorni, 35 Capricorni, χ Capricorni, θ Capricorni, 30 Capricorni, 33 Capricorni, ζ Capricorni, 19 Capricorni, 26 Capricorni, 27 Capricorni, 20 Capricorni, η Capricorni and 21 Capricorni.[9] Consequently, 36 Capricorni itself is represent the state Jin (Script error: No such module "Lang".)[10] (or Tsin),[11] together with κ Herculis in Right Wall of Heavenly Market Enclosure (asterism)[12]
