The asteroid belt formed from the primordial solar nebula as a group of planetesimals. Planetesimals are the smaller precursors of protoplanets. Between Mars and Jupiter, however, gravitational perturbations from Jupiter imbued the protoplanets with too much orbital energy for them to accrete into a planet.
There are six different stages in the condensation theory. These include the formation of a nebula cloud, the formation of a sun, the formation of planetesimals, the expulsion of gases from the forming sun, the growth of the planetesimals, and the formation of larger planets from planetesimals.
The crab nebula is the debris formed in the supernova explosion.
Neither; it is a star. it formed from a nebula.
Yes, a solar nebula is much larger than a neutron star. In terms of objects in space, neutron stars are tiny; only a few miles across. A stellar nebula such as the one that formed the sun is light years across.
The Crab Nebula was formed when it's host star exploded as a supernova [See related question]
Uranus was formed from the light gases of the outer solar nebula.
Prepositional phrases that begin with after are adverb phrases: e.g. "The nebula formed after a supernova" meaning the nebula formed afterward.
