In our solar system, the gas giant Jupiter has an estimated equatorial diameter of 143 000 km143\,000\text{ km}143000 km.
The Sun has an equatorial diameter that is 9.73 times the equatorial diameter of Jupiter. Calculate the equatorial diameter of the Sun, giving your answer in standard form to 3 significant figures.
One of Jupiter's Galilean moons, Europa, has a diameter that is 0.0218 times the equatorial diameter of Jupiter. Calculate the diameter of Europa, giving your answer to the nearest 10 km.
