In this exercise you will determine the angular width of various configurations of your out-stretched hand. You will be able to use this angular measure as a standard to measure the angular separation of distant objects, such as these paration between stars.

The units of S and R in the table below are to be the same, such that the units will cancel when you take the ratio of the two quantities. You will find centimeters or inches convenient to use.

The conversion factor transforming an angle measured in radians into degrees is:57.3 degrees/radian. This result from the fact that there are pi radians in 180degrees.Thus, 180 degrees/3.14 radians = 57.3 degrees/radian is the conversion factor.
