The solar system is filled with mystery and many unanswered questions. Below are two objects in our solar system. For each one, determine their average distance from the sun, and calculate their orbital periods using Kepler’s 3rd law. Then describe their compositions and compare them with each other. How are they different? How do they
describe the initial and current conditions of our solar system? How do the planets
nearest them compare to their compositions? Does it make sense to find these
astronomical bodies in their respective locations in the solar system? Finally based on
what you have learned thus far, what would you expect the theoretical Planet 9 to be
like in composition? Would it have an atmosphere? Explain concisely your reasoning.
