What angular dimensions will the Earth have when viewed from Venus when they are closest to each other? The radius of the Earth is 6400 km. The semi-major axis of the orbit of Venus is 0.7 AU.
decision
sin p = R / D; sin p = p / 206265, therefore R / D = p / 206265:
p = R * 206265 / DS = 6400 * 206265 / 0.3 * 1.5 * 10 ^ 3 = 29
