A binary star consists of two stars orbiting each other. Suppose a binary pair is known to be 580.0 light years away from Earth. How far apart are the two stars from each other, in light years, if they can just be resolved by a telescope with an aperture of 50 cm (0.50 m), using visible light (l = 550 nm)? (1 nm = 1 x 10-9 m)
