Acerca de Alnasl
Descripción
Alnasl (also spelled Nushaba) is an gigante naranja of tipo espectral K1III at magnitude 2.99 en Sagitario. Located a unos 96 anos luz de la Tierra, it has a luminosity of roughly 100 veces la solar. Alnasl marks the tip of the arrow in the Archer's bow and lies near the direction of the galactic center, making its field rich with background stars.
Consejos de Observación
Alnasl sits at the tip of the arrow/spout of the Sagittarius Teapot asterism. It is a good starting point for finding the rich star clouds, nebulae, and clusters near the galactic center. Its warm orange color provides a nice contrast to the blue-white star clouds behind it. Mejor observacion from June through September when Sagittarius is in the cielo nocturno.
Historia
The name Alnasl comes from the Arabic 'al-nasl,' meaning 'the arrowhead' or 'the point,' describing its position at the tip of the Archer's arrow. In the popular Teapot asterism, Alnasl marks the tip of the spout from which the Via Lactea appears to pour like steam.
Datos Curiosos
When you look at Alnasl, you are looking almost directly toward the center of our Via Lactea galaxy, which lies just a few degrees away in the dense star clouds of Sagittarius. The 'steam' rising from the Teapot's spout is actually the dense star clouds of the Via Lactea's central bulge.
