- Imagine that you visit a planet orbiting another star and discover that it is heavily cratered, but its small moon is nearly crater free. Why would that be a surprise? Speculate what might have happened to those objects.What is the Kuiper belt?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.
