Q1-Alpha Centauri is the closest star system (a triplet) and closest planetary system to Earth's Solar System at 4.37 light-years from the Sun. If Alpha Centauri A and B are orbiting each other where at their closest they are about 11 AU away from each other (1 AU = one astronomical unit = distance from Earth to Sun : 1.5 x 108 km). What is the smallest diameter of a radio telescope you need to be able to resolve these two stars as two separate stars in the radio band (with an average wavelength of 10 mm )? [hintz c = 3 x 105 km/s; 1 year: 365 days] The image 01' each object is a small Circular diffraction pattern.
