If Saturn is, on average, 9 times farther from the Sun than the Earth is, how long is its year in terms of Earth years?

We will use the formula (T_{1}^{2}) / (r_{1}^{3}) = (T_{2}^{2}) / (r_{2}^{3}) . If we substitute values as we know them, we get 1^{2}/1^{3} = x^{2}/9^{3} adius)em, we get s of Earth years?

from the Sun than the Earth is, how much longer is its year?

cause of , so we solve for x and get x = √ (9^{3}) = 27
