The system is drifting closer to the Sun with a radial velocity of −5 km/s.
The visible component is an A-type main sequence star with a stellar classification of A1 V; a class of star that is still fusing hydrogen at its core. It has around twice the mass and 2.2 times the radius of the Sun, and is shining with 18.6 times the Sun's luminosity. The effective temperature of the star's outer atmosphere is 8,846 K. Psi Scorpii is around 451 million years old and is spinning with a projected rotational velocity of 42.3 km/s.
