Part II. Significant Figures The significant figures in a number are all figures that are obtained from the measuring process and exclude those zeros that are included solely for the purpose of locating the decimal point. This definition will be clarified with a number of examples.

Given that the Diameter of Earth is about 7200 miles, how many Earths would fit across the Sun? You turn toward the east, seeing the full moon rising. You find that half of your finger tip at arm's length also covers the diameter of the Moon! Given that the diameter of the Moon is about 2160 miles, approximately how far from Earth is the Moon in miles and km according to your calculations?
