Unformatted text preview: can be simplified down to period #1 = period #2 Sqrt [(distance #1/distance #2) 3 ] OR period #1 = period #2 (distance #1/distance #2) 3/2 . Those of you with a scientific calculator (one that does powers, trig functions, scientific notation, etc.) will want to use the formula on the last line (remember that 3/2 = 1.5). Those with a calculator that just has a square root button will want to use the formula on the secondtolast line. If the satellite is orbiting the Sun, then the relation can be greatly simplified with an appropriate choice of units: the unit of years for the orbit period and the distance unit of astronomical units. In this case, the reference ``satellite'' is the Earth and Kepler's third law becomes period = distance 3/2 . Let's use this to find out how long it takes to explore the solar system....
