Problem 1
Aristarchus Method of Determining the Distance to the Moon
    Use Chis Cook's composite photograph of a lunar eclipse* to determine the radius of
the moon and its distance from the earth (in units of the radius of the earth). The sketch
below illustrates the appropriate geometry to use. Make use of small angle approximations.
a. Assume that only the darkest part of the Earths shadow (umbra) corresponds to total
eclipse. Draw a circle (with a compass if you have one) that best represents the umbral
shadow.
b. Note that the center of the shadow does not lie on the line connecting the path of the
cente
