 * Participants**: List the participants in this experiment.
 * Purpose**: The purpose of this lab is to use a sequence of images of the Galilean moons of Jupiter to calculate the mass of Jupiter.

Provide a short (one paragraph) description of what was done during this experiment. Supplement this description with images, video, etc. to make clear and interesting. Provide a short description of how the measurements of the period and the radius of the orbit allow you to find the mass of Jupiter. This may include a picture of a mathematical derivation if you like.
 * Brief Description of Experiment**:


 * Data**:





Create a table of data showing the time the images were taken and the distance from Jupiter of each of the moons. Be sure to include a heading for each column that includes the units of each measurement. Include a graph with fits that show the period and the radius of the oribt.

1 arc minute = 60 arc seconds 1 pixel = 0.63 arcsecs 1 radian = 57.3 degrees Distance of Jupiter from Earth for images jup5 to jup10 = 6.63 x 10^8 km 1 km = 1000 m ||
 * Sample Calculations:** These are the calculations that we used:
 * //Pixel to meter scaling:// || 1 degree = 60 arc minutes
 * Mass of Jupiter: || The mass of Jupiter is found by using the given 4pi squared and multiplying that by the radius of orbit of one of Jupiter's moons (D) cubed. This is then divided by the product of the constant of universal gravitation (G = 6.67 x 10^-11) and the time in seconds (T) it takes the moon to complete one orbit.

Mass of Jupiter = (4pi^2 x D^3) / (G x T^2) = 1.890798735 x 10^27 kg ||


 * Results**: Describe the major result of the experiment and how you arrived at this result. Typically, this will refer back to the purpose.


 * Lab Questions**: Write out and answer any questions that are in the "The Mass of Jupiter Unit" handout.


 * Conclusion**: A good conclusion will include:
 * A statement about whether you think that the experiment produced a valid and reproducible result and reasoning supporting your statement.
 * A suggestion as to why your experimental results differ from any accepted value or your expected result (if appropriate).
 * A suggestion for a simple improvement to the experiment. Think about what caused problems, measurement inaccuracies, or inappropriate simplifying assumptions and propose a change. A sketch may be helpful.
