It is a well known fact that during a total solar eclipse the disk of the moon almost completely covers the disk of the Sun. From this fact and from the information you can gather from examples 2.3 and 2.4, determine the approximate diameter of the moon.
Distance of the Moon from the Earth = 3.84 × 108
Distance of the Sun from the Earth = 1.496 × 1011
Diameter of the Sun = 1.39 × 109
During a lunar eclipse, the position of the sun, moon and earth is as shown below:
