Suhail Hadar — Estrella en Popa

Naos (also known as Suhail Hadar) is one of the hottest and most luminous stars visible to the simple vista. At tipo espectral O5Iaf and magnitude 2.25, it is a supergigante azul with a temperatura superficial of about 42,000 K and a luminosity roughly 800,000 times that of el Sol. Located aproximadamente 1,080 años luz away, Naos has a powerful viento estelar that ejects mass at a rate millions of times greater than el Sol's solar wind.

Located in the southeastern part of Puppis, Naos is a striking blue-white star best viewed from the hemisferio sur or from low latitudes boreales. It sits in a rich part of the Vía Láctea with many background stars. Prismaticos reveal its vivid blue-white color against the star-rich backdrop. Mejor observación from January through April. From northern mid-latitudes it is low on the southern horizon.

The name Naos comes from the Greek 'naos,' meaning 'ship,' referring to the constellation Puppis (the stern of the mythological ship Argo). The alternate name Suhail Hadar is Arabic in origin. Zeta Pup was one of the first stars whose extreme temperature was determined spectroscopically, revealing it as an O-type supergiant — among the most massive and energetic stars known.
