Chapter 14, Problem 19E

Present theory suggests that giant planets cannot form without condensation of water ice, which becomes vapor at the high temperatures close to a star. So how can we explain the presence of jovian-sized exoplanets closer to their star than Mercury is to our Sun?

Blurred answer

Why do astronomers conclude that none of the Jovian planets' rings can be left over from the formation of the planets?
How would the solar system be different if the solar nebula had cooled, with a temperature half its actual value? [select all that apply]    options:   There would be more comets.   Life would have been very unlikely to evolve here.   There would be no comets.   There would be fewer asteroids.   There would be more asteroids.   Jovian planets would have formed closer to Sun.   Terrestrial planets would be large
Imagine a trans-Neptunian object with roughly the same mass as Earth but located 50 AU from the sun. a) based on the solar nebula theory, what do you think this object would be made of and why? b) on the basis of speculation, assume a reasonable density for this object and calculate its diameter in units of Earth radii.
