SOLUTION TO EXERCISE 5
(a) As with exercise 4(b) above, x 3480 km -------- = --------- so x = (3480 * 57.3)/384000 = 0.52 deg of arc. 57.3 deg 384000 km (b) Exercise left to the reader. (c) As with Part (a) above, x 1.39 * 106 km -------- = ------------- so x = 0.53 deg of arc. 57.3 deg 1.50 * 108 km (d) The Moon and the Sun are almost exactly the same angular size on the sky. Thus, if the Moon moved directly between Earth and the Sun, the resulting eclipse could be quite beautiful. |
