Zeta<sup>2</sup> Scorpii (Zeta<sup>2</sup> Sco, ö<sup>2</sup> Scorpii, ö<sup>2</sup> Sco) is a star in the constellation of Scorpius. With an apparent visual magnitude variying s between 3.59 and 3.65, this star is visible to the naked eye. Parallax measurements derive a distance of 135 light-years to the star.
The spectrum of this star matches a spectral class of K4 III, with the luminosity class "III" classifying it as a giant star that has exhausted all the hydrogen at its core and has expanded. Around six billion years old, this 1.18-solar mass star has swollen to 18.7 solar diameters and now radiates 130 times the Sun's luminosity from its photosphere. The effective temperature of the star has cooled to , giving it the orangish hue typical of a K-type star.
Zeta2 is located near the blue-white supergiant star ö<sup>1</sup> Scorpii in Earth's sky. In astronomical terms, ö<sup>2</sup> is much closer to the Sun and unrelated to ö<sup>1</sup> except for line-of sight co-incidence. ö<sup>1</sup> is about 6,000 light-years away and probably an outlying member of open star cluster NGC 6231 (also known as the "northern jewel box" cluster). ö<sup>2</sup> can also be distinguished from its optical partner, ö<sup>1</sup>, because of its orangish colour especially in long-exposure astrophotographs.
