  The moon measures about 2160 miles (3476 km) across. The distance is about one fourth the diameter of the Earth, and 400 times smaller than that of the sun.
Example: A Theoretical System The Radius of a moon is 1500 miles. (This is bigger than our moon) The Distance to this moon is 300,000 miles. 1500 = 0.005 This number is the (Tangent of Theta) 300,000 2 Multiply 0.005 by 2 to get the Tangent of Theta.
