Iklil: The Crown of the Scorpion
In the tapestry of the night sky, the constellation Scorpius, the scorpion, is a captivating sight. Among its many bright stars, one stands out for its prominence and association with ancient Arabic astronomy – Iklil. This Arabic name, meaning "crown," is given to the star i Scorpii, a bright blue giant shining with a magnitude of 2.99.
Iklil-al-Jebhah, meaning "the crown of the forehead," is a more elaborate term that highlights the star's position within the scorpion's celestial anatomy. It occupies the space just above the scorpion's "head," creating a visual crown atop the creature's fierce visage.
