question 217

Multiple Choice

Kepler's third law for orbits around the Sun is a³ = P²,where the semi-major axis a is in AU and the period P is in years.(See section 2-5 in Discovering the Essential Universe,6th ed.) .For objects in orbit around Jupiter we must use a³ = 0.001 P² because the mass of Jupiter in solar masses is approximately 0.001.The period for Comet Shoemaker-Levy 9 in its orbit around Jupiter was about two years.What was its maximum distance from Jupiter in this orbit (in AU) ?

• A) 0.05
• B) 0.16
