Iot-1

Its story

Iota-1 Scorpii burns as a yellow-white F2 Ia supergiant —a rare luminous class shining with around 35,000 times the Sun's energy from 1,930 light-years away. Its swollen radius spans more than 120 solar radii, and its twelve solar masses place it in the quiet catalogue of stars destined for spectacular endings. It also forms an optical pair with Iota-2 Scorpii, two distant beacons in the Scorpion's stinger.
