the planet Mars has a diameter of approximately 6,780 kilometers (S = 6.78 ✕ 103 km). When it is nearly as close to Earth as it ever gets, it lies about 54,600,000 km away (r = 5.46 ✕ 107 km). The human eye can resolve details down to an angular limit of one arc minute (1'). calculate the angular diameter of Mars, in radians, when closest to Earth.
