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? The spinning cloud moved toward a massive star which became the sun, and the dust particles were compressed to form planets. Centripetal force pulled surrounding stars and asteroids into the revolving mass, and these ultimately formed the sun and planets. A black hole formed, pulling toward it nearby stars and asteroids which became the sun and planets. Gravitational force compressed the matter into planets and caused a fusion reaction which formed the sun.

'Gravitational force compressed the matter into planets and caused a fusion reaction which formed the sun.'
Explicación
## Step 1The problem is about the formation of the solar system, which is a topic in astronomy. The question asks us to identify the correct sequence of events according to the nebular hypothesis, which is the most widely accepted theory about the formation of the solar system.## Step 2The nebular hypothesis suggests that the solar system originated from a spinning cloud of dust and gases, which is the remnants of a star explosion. This cloud is known as a nebula.## Step 3The next step in the formation of the solar system, according to the nebular hypothesis, is the gravitational collapse of this nebula. This means that the gravitational force within the nebula caused the matter to come together and form a dense, hot core.## Step 4The dense, hot core eventually became the sun. The remaining matter in the nebula, under the influence of gravity, began to orbit around the sun. Over time, these particles of matter came together to form the planets.
