Kepler's third law, (in photo) can be
used to calculate the time it takes for a planet to complete one orbit of a star. The average radius of the planet's orbit in km is r, K is a constant that changes depending on the mass of the star and T is the time it takes in years. Calculate the value of K if it takes earth one year to go around the sun, and earth is, on average, 1.51 x 10^8 km from the sun.
