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.
There is one part to this question. I need to know the days. Thank you!

- Upload a PDF document that shows your work and solution. - 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 47² )3 to relate 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 d nm.arrow_forwardIf you could visit another planetary system while the planets are forming, would you expect to see the condensation sequence at work, or do you think that process was most likely unique to our Solar System? How do the properties of the extrasolar planets discovered so far affect your answer? Do you expect the most planetary system in the Universe have analogs to our Solar System’s asteroid belt and Kuiper Belt? Would all planetary systems show signs of an age of heavy bombardment? If the solar nebula hypothesis is correct, do you think there are more planets in the Universe than stars? Why or why not?arrow_forwardSome astronomers argue that Jupiter and Saturn areunusual, while other astronomers argue that all solarsystems should contain one or two such giant planets.arrow_forward
