Astronomers have discovered a planetary system orbiting a star, which is at a distance of 5.5 x 1017 m from the earth. One planet is believed to be located at a distance of 2.0 x 1010 m from the star. Using visible light with a vacuum wavelength of 550 nm, what is the minimum necessary aperture diameter that a telescope must have so that it can resolve the planet and the star?
