Star in the constellation Capricornus
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.

In
Chinese , 哭 Kū
Crying , refers to an asterism consisting of μ Capricorni and
38 Aquarii .
[10] Consequently, the
Chinese name for μ Capricorni itself is 哭一 Kū yī the First Star of Crying .).
[11] From this Chinese name, the name Kuh has appeared.
