HD 32518 (HR 1636) is a solitary star in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 6.42, placing it near the max naked eye visibility. Located about 400 light years away, it is receding with a heliocentric radial velocity of −7.02 km/s. HD 32518 has a stellar classification of K1 III, indicating that it is an orange giant star. Located in the cool end in the red clump, the object is currently on the horizontal branch. At present it has 1.2 the mass of the Sun but has expanded to a radius of 10.8 R☉. It shines at 46.4 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,731 K, giving it an yellowish orange glow. HD 32518 is older than the Sun with an age of 6.4 billion years and spins slowly with a projected rotational velocity of 1.2 km/s−1. However, this amount is poorly constrained. As for its metallicity, studies place it around solar level. (en) HD 32518は、きりん座の方角に約390光年の距離にある、6等級のK型巨星である。太陽と比べ、1.13倍質量が大きく、10.22倍大きく、46.4倍明るい。しかし、金属量は太陽より少なく、年齢も太陽よりやや上とみられる。 (ja) Mago eller HD 32518 är en ensam stjärna i den mellersta delen av stjärnbilden Giraffen. Den har en skenbar magnitud av ca 6,43 och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 8,2 mas, beräknas den befinna sig på ett avstånd på ca 400 ljusår (ca 123 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -7 km/s.
