Pi Scorpii is a triple star system in the constellation Scorpius. It is approximately 459 light years from Earth.

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.
