Question

most astronomers believe that the solar system originated when a star exploded, forming a spinning cloud of dust and gases. according to this theory, what occurred next? centripetal force pulled surrounding stars and asteroids into the revolving mass, and these ultimately formed the sun and planets. the spinning cloud moved toward a massive star which became the sun, and the dust particles were compressed to form planets. gravitational force compressed the matter into planets and caused a fusion reaction which formed the sun. a black hole formed, pulling toward it nearby stars and asteroids, which became the sun and planets.

Explanation:

In the widely - accepted nebular hypothesis, after a star exploded forming a spinning cloud of dust and gases, gravitational force compressed the matter. The denser regions of the cloud collapsed under their own gravity to form the sun through a fusion reaction, and the remaining matter coalesced into planets. Centripetal force is related to circular motion and not the main force in the initial formation of sun and planets from the nebula. The spinning cloud did not move towards a pre - existing massive star to form the sun. A black hole is not part of the standard solar - system formation theory from a nebula.

Answer:

Gravitational force compressed the matter into planets and caused a fusion reaction which formed the sun.
