Can objects in the Kuiper belt or the Oort cloud form into whole rocky planets? Why or why not?
Given the trillions of objects orbiting the sun in the Asteroid, Kuiper-Edgeworth and Oort Belts, why haven't more coalesced to form planets?
Why don't planets hit each other? (Even there's gravity) Why do planets orbit stars? Why do exactly planets revolve around the sun? Why do the asteroids in the asteroid belt not acrete? Why can't planets be different shapes? Why don't planets have phases like the moon? What is the point of all the other planets? Are all planets round and why? Why are planets mostly round? Why do all of the planets revolve around the sun in the same direction? Why don't we have a base on the moon? Why are most planets sphere? Why do the planets in our solar system circle the sun? Why all the planets in our solar system, are round? Why don't we load the earths trash on earth and launch it into space or toward the sun? What's the point of existence of other planets? Why do the planets in our solar system orbit along the same plane? Why all planets are circling the sun in the same direction? Why don't space organizations try to send spacecraft to planets like Neptune or Pluto? Why all the planets of this solar system are moving in the same direction around the sun? Why are most planet orbits in our solar system on relatively the same 2D plane? Why do all planetary systems orbit stars? Why are all the planets and moons round? Why is there an asteroid belt? Why are the inner planets rocky and the outer planets large gas giants? Why don't gas planets have gas moons? Will gravity eventually pull the asteroid belt together to form a planet? Why are all planets spheres? Why doesn't the sun have a solid core? Shouldn't have all of the heaviest elements in the primordial solar system coalesced into the center? The planets revolve around the sun without losing energy when gravitational force is acting on them .why?
