Mu Capricorni (μ Cap, μ Capricorni) is a solitary[9] star in the southern constellation of Capricornus. Based upon an annual parallax shift of 37.57 mas as seen from the Earth,[1] the star is located about 87 light years from the Sun. It is visible to the naked eye with an apparent visual magnitude of +5.081.[2]

It is a yellow-white hued, F-type main sequence star with a stellar classification of F2 V.[3] It is an estimated 1.6[4] billion years old and is spinning with a projected rotational velocity of 69 km/s.[7] The star has 1.29[5] times the mass of the Sun and around 1.8[6] times the Sun's radius, with an effective temperature of 6,892 K.[5]

In Chinese, Script error: No such module "Lang". (Script error: No such module "Lang".), meaning Crying, refers to an asterism consisting of μ Capricorni and 38 Aquarii.[10] Consequently, the Chinese name for μ Capricorni itself is Script error: No such module "Lang". (Script error: No such module "Lang"., Template:Langx.).[11] From this Chinese name, the name Kuh has appeared.[12]
