Chapter 10, Problem 4TQ
Approximate the Roche limit as 2.44 times a planet’s radius. Using appendix tables 3 and 5, calculate the Roche limit distances for Saturn and Uranus and make a list of the moons found inside these distances. How it is possible for these moons to orbit there? Would you expect these moons to be spherical or irregular? Why?

What is the observed angular speed of
Neptune, along the ecliptic of Earth, when it is
at opposition, in units of arc minutes / day?
Presume the orbits are circular. Earth has
orbital speeds of 30km/s and Neptune has
5.43km/s, Neptune here has orbital radius
30.1 AU. Now looking at Uranus for the same
condition, in what direction along the ecliptic
will it be traveling?
I would like you to compare the size of some of the largest moons of the solar system to their host planets. Using diameters of 12,700 km, and 140,000 km, 116,000 km for Earth, Jupiter, and Saturn respectively, please provide the ratios of the following moons to their host planets (you can use Table 12.1 from the book to get the diameters of the moons): Luna (Earth's moon), Io, Callisto, Ganymede, Europa, and Titan. After collecting those ratios, please tell me one thing that you notice that stands out about those results.
