I asked a question on main about creating a planet from the asteroid belt. On being informed that the main asteroid belt contains nowhere near enough material, I expanded this to include the trojan asteroids and the Kuiper belt. I had miscalculated the mass of the Kuiper belt and was informed that the total mass was still only 10% of Earth's.
I can continue including more mass but the question is becoming not only different from its original form, but also more broad as it's now taking mass from a wide variety of solar system resources which all require different approaches.
Is it useful to leave my question as it is, with the existing answer that explains clearly why there is not enough mass? If I leave it as is, should I change the title to include reference to the asteroid belt?
