Zeta2 Scorpii (Zeta2 Sco, ζ2 Scorpii, ζ2 Sco) is a K-type orange giant star in the constellation of Scorpius. It has an apparent visual magnitude which varies between 3.59 and 3.65, and is located near the blue-white supergiant star ζ1 Scorpii in Earth's sky. In astronomical terms, ζ2 is much closer to the Sun and unrelated to ζ1 except for line-of sight co-incidence. ζ1 is 5,700 light-years away and probably an outlying member of open star cluster NGC 6231 (also known as the "northern jewel box" cluster), whereas ζ2 is a mere 132 lightyears distant and thus much less luminous in real terms. ζ2 can also be distinguished from its optical partner, ζ1, because of its orangish colour especially in long-exposure astrophotographs.

  • Zeta2 Scorpii (ζ2 Sco / ζ2 Scorpii) è una stella nella costellazione dello Scorpione di magnitudine 3,62. Si trova apparentemente vicina in cielo a Zeta1 Scorpii, anche se in realtà le due stelle non sono fisicamente legate tra loro, in quanto Zeta1 è una supergigante blu che si trova molto più distante, a 5700 anni luce di distanza dalla Terra, e fa parte probabilmente dell'ammasso aperto NGC 6231, mentre Zeta2 Scorpii è a soli 151 anni luce di distanza, e quindi in realtà molto meno luminosa di Zeta1, dalla quale si distingue in particolar modo per il colore giallo arancione.

  • 전갈자리 제타2는 전갈자리 방향으로 지구로부터 약 151 광년 떨어져 있는 K형 거성이다. 제타2의 겉보기 등급은 3.59에서 3.65까지 변화한다. 밤하늘에서는 청백색 초거성 전갈자리 제타1 옆에 있는 것처럼 보이나 둘은 서로 관계가 없는 독립 천체이다. 천문학적 용어로 말하자면 제타2는 제타1에 비해 지구로부터 훨씬 가깝고 단지 우리의 시선방향과 나란히 놓여 있는 것일 뿐이다. 제타1은 지구에서 5,700 광년 떨어져 있으며 산개성단 (북쪽하늘의 보석상자)의 일원이나, 제타2는 지구로부터 151 광년 떨어져 있어 상대적으로 가까우며, 눈에는 제타1보다 밝게 보이나 실제 광도는 훨씬 낮다. 장시간 노출 사진을 찍으면 제타2는 오렌지색으로 빛나므로 제타1과 구별된다.
