kepler’s Third Law Kepler’s Third Law of planetary motion states that the square of the period T of a planet (the time it takes for the planet to make a complete revolution about the sun) is directly proportional to the cube of its average distance d from the sun. Find the constant of proportionality by using the fact that for our planet the period is about 365 days and the average distance is about 93 million miles

kg is the mass of the sun, 
is the gravitational constant, and 
is the period of the planet’s orbit (in seconds). Use the fact that the period of the earth’s orbit is about 365.25 days to find the distance from the earth to the sun.
