Q Scorpii, also designated as HD 159433, is an astrometric binary (100% chance) located in the southern zodiac constellation Scorpius. It has an apparent magnitude of 4.27, making it readily visible to the naked eye under ideal conditions. It lies in the tail of Scorpius, between the stars λ Scorpii and μ Scorpii and is located 7′ away from the faint globular cluster Tonantzintla 2. Based on parallax measurements from Gaia DR3, the system is estimated to be 158 light years distant, but is approaching the Solar System with a heliocentric radial velocity of −49 km/s.

  • Q Scorpii (Q Sco)​​ es una estrella de la constelación de Escorpio.Tiene magnitud aparente +4,27 y se encuentra a 166 años luz de distancia del Sistema Solar. Q Scorpii es una gigante naranja de tipo espectral K0IIIb​ con una temperatura superficial de 4596 K.Con una luminosidad equivalente a la de 44 soles, su masa solo es un 30% mayor que la masa solar.​La medida de su diámetro angular —2,15 ± 0,13 milisegundos de arco—​ permite evaluar su diámetro real, resultando ser unas 12 veces más grande que el diámetro solar, un tamaño relativamente habitual en esta clase de estrellas.Sus características son parecidas a las de otras conocidas gigantes de tipo K como Pólux (β Geminorum), Menkent (θ Centauri) o φ2 Orionis, si bien la mayor distancia a la que se halla Q Scorpii hace que sea menos bri (es)
