PI SCORPII

'Pi Scorpii' is a triple star system in the constellation Scorpius. It is approximately 459 light years from Earth.
'Pi Scorpii A' is a contact binary of the Beta Lyrae type. Both its members are hot, blue-white B-type dwarfs. Together they have a mean apparent magnitude of +2.89. Their rotation period is 1.57 days and they are separated by a distance of only 15 solar radii. Rotation causes their apparent magnitude to vary between +2.87 and +2.92.
They are orbited by a more distant companion designated 'Pi Scorpii B', which has an apparent magnitude of +12.2. This distant companion is separated from the primary binary by 50 arcseconds, putting it at least 7000 Astronomical Units away.
