Beta Scorpii

Beta Scorpii(? Scorpii) este un sistem stelar din constelatia Scorpius(Scorpionul). A fost traditional denumita Acrab, Akrab sau Elacrab, toate provenind din limba araba, unde� ??????? al-’Aqrab, impartind acest nume cu Xi Scorpii.


Observata printr-un telescop mic, Beta Scorpii se vede ca o stea binara, aflate la 14 arcsecunde distanta una de alta. Amandoua sunt stele fierbinti, de tip B, cu o masa de 10 ori mai mare ca Soarele.


Din cauza apropierii fata de eliptica, Beta Scorpii poate fi ocultata de Luna, si foarte rar de planete. Ultima ocultatie facuta de o planeta a fost facuta in 13 mai 1971 de Jupiter.
