Refer to the following information for the next four questions.

Halley's comet has a period of 76 years, and its orbit has an eccentricity of 0.97. Use the fact that Kepler's constant is equal to 1 for satellites in our solar system when their periods are given in terms of earth years and their distances in terms of astronomical units.

Refer to the following information for the next two questions.

With the information given, determine Kepler's constant for each planet and then determine the experimental percent error for the given data against the accepted value of 1.

Uranus: period = 84.013 yr R_{AV} = 19.19 AU e = 0.047
