THE MASS OF JUPITER Lab Instructions OBJECTIVES To determine Jupiter's mass by studying the orbital motion of Jupiter's moons. This will also demonstrate the value of Newton's theories and how they can be applied to calculate the mass of distant objects. EQUIPMENT The Stellarium program on your computer. Calculator capable of doing exponential notation. Metric ruler with millimeter and centimeter markings. INTRODUCTION Exponential Calculations It is important to be comfortable with exponential notation (also called powers-of-ten notation or scientific notation) to do this lab. Therefore, here is a summary of ideas to help you use your calculator efficiently for working with very large numbers. Since each calculator does not have the same keys, you should practice on your own calculator to ensure you know how it functions. In one hour, there are 3600 seconds, which can be written many different ways: 3.6 x 1000 = 3.6 x 10' = 3.6 x 10^3 = 3.6 EXP 3 = 3.6 EE 3
