One of Kepler's three laws of planetary motion states that the square of the period, P, of a body orbiting the sun is proportional to the cube of Its average distance, d, from the sun. The Earth has a period of 365 days and its distance from the sun is approximately 93,000,000 miles. (a) Find P as a function of d. P(d) = squareroot (1.6563*10^(-19)d) (b) The planet Uranus has an average distance from the sun of 1, 800,000,000 miles. How many earth days are In a Uranus year in other words, what is the period of the planet Uranus? days (Round to nearest day and do not enter commas in your answer.)
