Its story

22 Scorpii is a blue sun barely ten million years old, set in the body of the Scorpion, with four and a half solar masses and roughly 600 times the Sun's luminosity. It spins at 169 km per second at its equator —fast enough to flatten its shape— and burns in the deep blue typical of type B3. At 413 light-years, its magnitude-4.79 glow trails the Scorpion's tail through northern summer nights.
