[2] It is drifting further away with a radial velocity of +23 km/s. [2]
This object has been stellar classifications of A1III [3] and A0 II, [4] matching a massive A-type giant or bright giant star, respectively. It is an estimated 31 [5] million years old and is spinning with a projected rotational velocity of 30 km/s. [8] The star has 8.6 [5] times the mass of the Sun and around 4.5 [6] times the Sun's radius. The star is radiating 8,670 [2] times the Sun's luminosity from its photosphere at an effective temperature of 8,023 K. [7]
Psi Scorpii, which is Latinized from ψ Scorpii, is a star in the zodiac constellation of Scorpius.

This object has a white hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.35. Based on parallax, it is located at a distance of approximately 1,360 light years from the Sun. It has an absolute magnitude of −3.75, and is drifting further away with a radial velocity of +22.5 km/s.
HD 102776, also known by its Bayer designation j Centauri, is a suspected astrometric binary star system in the southern constellation of Centaurus. It has a blue-white hue and is faintly visible to the naked eye with a typical apparent visual magnitude of 4.30. The distance to this star is approximately 600 light years based on parallax, and it is drifting further away with a radial velocity of ~29 km/s. It is a member of the Lower Centaurus Crux subgroup of the Sco OB2 association. HD 102776 has a relatively large peculiar velocity of 31.1 km/s and is a candidate runaway star that was ejected from its association, most likely by a supernova explosion.
HD 125288 is a single star in the southern constellation of Centaurus. It has the Bayer designation v Centauri ; while HD 125288 is the star's identifier in the Henry Draper catalogue. The object has a blue-white hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.30. Based on parallax measurements, it is located at a distance of approximately 1,230 light years from the Sun.
