The mass of Saturn is 5.686 * 10^26 tonnes. The mass of Earth is 6.04 * 10²¹ tonnes. How many times heavier is Saturn than Earth? Give your answer in standard form to a suitable degree of accuracy.

We simply divide the mass of Saturn with the mass of Earth.

5.686 x 10^26 / 6.04 x 10^21

The rule of significant figures when dividing numbers is that the least amount significant figures must be used in the quotient.

Therefore, Saturn is 9.41 x 10^4 times heavier than Earth.
