Star in the constellation Phoenix
μ Phoenicis ,
Latinized as Mu Phoenicis , is a suspected
astrometric binary
[10]
star system in the southern
constellation of
Phoenix . It is visible to the naked eye as a faint, yellow-hued star with an
apparent visual magnitude of 4.59.
[2] This system is located approximately 246
light years distant from the Sun based on
parallax ,
[1] and is drifting further away with a
radial velocity of +17.4 km/s.
[4]
The visible component is an aging
G-type
giant star with a
stellar classification of G8III.
[3] Having exhausted the supply of hydrogen at its
core , this star cooled and expanded off the
main sequence . At present it has 13
[4] times the girth of the Sun. It is 1.4
[6] billion years old with 2.5
[6] times the
mass of the Sun . It is radiating 97
[4] times the
luminosity of the Sun from its swollen
photosphere at an
effective temperature of 4,900 K.
