SUMMARY
The discussion focuses on calculating the minimum distance between two stars for them to be perceived as distinct using a telescope with a circular aperture of 2.5 meters and a wavelength of 463 nm. The formula used is angle = 1.22 x (wavelength/diameter), leading to an angle of approximately 2.259 x 10-7 radians. Multiplying this angle by the distance to the stars (1022 meters) results in a minimum separation of approximately 2.259 x 1016 meters for the stars to be viewed as separate entities.
