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?

The spinning cloud moved toward a massive star which became the sun, and the dust particles were compressed to form planets.

A black hole formed, pulling toward it nearby stars and asteroids, which became the sun and planets.

Centripetal force pulled surrounding stars and asteroids into the revolving mass, and these ultimately formed the sun and planets.

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

The correct description of what occurred next according to the widely accepted theory of solar system formation, known as the nebular hypothesis, is:

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

In this process, the spinning cloud of dust and gas (the solar nebula) collapsed under its own gravity, leading to the formation of the sun at its center. As the material continued to clump together, it formed the planets, moons, asteroids, and other bodies in the solar system. The gravitational forces played a crucial role in the compression and accretion of materials, leading to the fusion reactions that ignited the sun.
