Q Scorpii

Q Scorpii (Q Sco) is an orange giant star in the constellation Scorpius. Its apparent magnitude is 4.27. It lies in the tail of Scorpius, between the stars λ Scorpii and μ Scorpii, from the faint globular cluster Tonantzintla 2.
Q Scorii is a suspected astrometric binary, a star whose position is seen to oscillate although no companion has been detected. From Hipparcos data, its proper motion is seen to be discrepant and accelerating, although there is insufficient data to determine any orbit.
Q Scorpii is cooler than the sun, but more luminous. It is a red clump giant, at the cool end of the horizontal branch, fusing helium in its core. Like all red clump giants, it has an effective temperature near and a bolometric luminosity of around .
