Textbook Question
Chapter 13, Problem 19E
We believe that chains of comet fragments like Comet Shoemaker-Levy 9’s have collided not only with the jovian planets, but occasionally with their moons. What sort of features would you look for on the outer planet moons to find evidence of such collisions? (As an extra bonus, can you find any images of such features on a moon like Callisto? You can use an online site of planetary images, such as the Planetary Photojournal, at photojournal.jpl.nasa.gov.)

Consider an asteroid that orbits in a relatively circular orbit with a semimajor axis a = 2 au
from the Sun. A typical asteroid has an albedo, or reflectivity, A ~ 0.3. At our closest
approach to the asteroid, we make a measurement of the flux coming from the asteroid to
be F = 3 × 10-15 w m-2. What is the radius of the asteroid in km? Include a labelled
diagram along with your calculations.
Why do astronomers conclude that none of the Jovian planets' rings can be left over from the
formation of the planets?

Consider a moon of Uranus if Uranus is currently a distance of 2.08 billion km from Earth, then
what diameter telescope would you need (use telescope-resolution formula = 1.22, where D
is the telescope diameter) in order to clearly resolve the moon Titania in orbit around Uranus if the

moon has a period of orbit of T = 8.71 days? (use Kepler's 3rd Law T² = (GMrave
T2
moon's period T to moon's orbital radius, r) The telescope only needs to resolve the small dot of the
moon as distinct from the circle of light which is Uranus, so the orbital resolution is the angular size
of the diameter of orbit of Miranda (use the arc-length formula 0 = 2 where d is the distance from
Earth to Uranus). Take the mass of Uranus as 8.68 × 1025 kg, and the wavelength of light as 490
