Acrab

Its story

Acrab marks one of the Scorpion's claws, burning as a hot blue star some 404 light-years away. Its name comes from the Arabic «al-ʿaqrab», simply «the scorpion», and modern astronomers found that what looks like a single point of light is in fact a complex system of several blue suns wheeling around one another. Its light set out when Galileo had only just begun pointing his telescope at the sky.
