Ozarks Technical Community LES4 Orbits and Keplers Law Astronomy Lab 5.
The goal of this activity is to test Kepler’s third law.
For each semimajor axis given in the table, use the stopwatch in the tool from Lesson 4 (shown below in
Figure 5-5) to time the orbital period. Then test Kepler’s third law.
Question 1: Do the squares of the periods seem to come out close to equal to the cubes of the semimajor axes?
Question 2:Why do you think some of the squared periods and cubed semimajor axes came out very close but
not exactly the same?
