The Moons of Jupiter
Question1
You should be able to decide how many lines of data are needed for each moon if you plot a
rough graph as you go along. Ideally you should have at least one full sine curve (peak to peak)
for each moon, but it is up to you to decide whether or not this is possible.
From the above animation it can be seen that as the position of a body orbiting another is measured,
when plotted against time, a sine wave is produced. This effect can also be seen when
measuring the distance of an orbiting body from it's parent when the plane of the system is seen
edge on.
Using the Jupiter Moon Rotation Laboratory software the object of this exercise is to measure the
orbits of the four main moons of the Jupiter system namely Io, Europa, Ganymede and Callisto.
When the curves for the various moons are plotted it will, using Kepler's third law of planetary motion,
be possible to determine the mass of Jupiter.
