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.
If 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?
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.
