Orion's Belt is an asterism in the constellation of Orion. Other names include the Belt of Orion, the Three Kings, and the Three Sisters. The belt consists of three bright and easily identifiable collinear star systems – Alnitak, Alnilam & Mintaka – nearly equally spaced in a line, spanning an angular size of ~140′ (2.3°).
Owing to the high surface temperatures of their constituent stars, the intense light emitted are blue-white in color, aiding in the recognition of the familiar astronomical motif. In spite of their spot-like appearance, only Alnilam is a single star; Alnitak is a triple star system, and Mintaka a hextuple. Each of the three owe their luminosity to the presence of one or more blue supergiants. The brightest as viewed from Sol is Alnilam, with an apparent magnitude of 1.69, followed by Alnitak at 1.74 and Mintaka at 2.25. Together, the 10 stars of the three systems has a combined luminosity of nearly one million times (~970,000) that of the Sun's.
Orion's Belt has been called various names and mentioned in various cultures and literature. It has played a central role in astral navigation in the Northern hemisphere since prehistoric times, being readily pointed out by even the most unstarwise wayfarer. As a matter of fact, it is often considered by astronomers to be among the clearest constellations in the Winter sky, although it is not visible during Summer, when the Sun is too visually close.
Musicians also admire this asterism, dedicating works to it that become truly beloved by listeners. And here is one of my favourite tracks from the new Celcius album, reflecting all the splendor and importance of the Orion's Belt! So go ahead, to the bright stars! The flight is normal, everything is great!
Glory, Glory, SpaceSynth! 🚀
