Stea dublă

În astronomie, o stea dublă reprezintă o pereche de stele care văzute printr-un telescop optic apar ca fiind foarte apropiate. Dacă stelele sunt conectate gravitațional una de cealaltă se poate vorbi de un sistem binar sau de o stea binară; iar dacă nu sunt conectate și sunt la distanță mare apărând împreună doar din cauza alinierii observatorului terestru, atunci ansamblu se numește stea dublă optică[1][2]. Stelele binare sunt importante în astronomie, deoarece permit calcului direct ai masei stelare și al altor parametrii.
