  HD 49947 (HR 2531) is a solitary star in the southern circumpolar constellation Volans. It has an apparent magnitude of 6.36, placing it near the max naked eye visibility. Parallax measurements place the object at a distance of 459 light years but is receding with a heliocentric radial velocity of 15.88 km/s
  
  HD 49947 has a stellar classification of G8 III and is a red clump giant, meaning that it is located on the warm end of the horizontal branch. At present it has double the mass of the Sun and at an age of 1.27 billion years, has expanded to an enlarged radius of 10.33 solar radii. It radiates at 61 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,964 K, giving a yellow hue. HD 49947 is metal deficient with an iron abundance 68% that of Sun and spins very slowly.
