Investigating the Rotational Frequencies and Orbital Periods of Jupiter's Moons

This study aimed to determine the rotational frequencies of Jupiter's moons, specifically Europa and Callisto, and assess their orbital periods. Using a photometer attached to a 20" telescope, we measured the relative brightness of the moons to identify distinctive brightness patterns. Additionally, a 12" telescope with a CCD camera was utilized to photograph Jupiter and its moons, allowing us to track their return to original positions over time. Unfortunately, much of our data was corrupted, hindering our ability to reach conclusive results.

  1. Galilean Orbiting Object's Frequencies GOOF

  2. Original Objective • To determine the rotational frequencies of Jupiter's moons • Also to determine to orbital periods of the Moons

  3. What We Tried To Do • Measure the relative brightness of two of Jupiter's moons, Europa and Callisto using the photometer and the 20” telescope. • This would allow us to determine the rotational period of these two moons by determining how long it took to form a distinctive pattern.

  4. More of What We Tried To Do • Using the 12” and a CCD camera, we attempted to take pictures of Jupiter (and its moons) to determine the orbital period of the moons. • By seeing when the moons came back into original positions, then we could determine how long the moons took to orbit Jupiter.

  5. What Happened...

  6. “Results” • Most of the data was corrupted. • Both the data for the comparison star that we used (SAO 187992) and the data for the moons fluctuated in weird ways...

  7. Day 1 • Comparison Star, then Europa and Callisto

  8. Day 2 • Again, the comparison star and the 2 moons.

  9. Day 3 • DANCE PARTY!!! • and then cloudy data. cry. • Finally, robotic beings rule the world. • Woohoo

  10. So.. • In the end, we just got unlucky. But that's the way it goes.
