The drawing (not to scale) shows one alignment of the sun, earth, and moon. The gravitational force FSM that the sun exerts on the moon is perpendicular to the force FEM that the earth exerts on the moon. The masses are: mass of the sun = 1.99 1030 kg, the mass of earth = 5.98 * 10^24 kg, mass of moon = 7.35 * 10^22 kg. The distances shown in the drawing are rSM = 1.50 1011 m and rEM = 3.85 108 m.
