- Which of the following statements about the formation of the solar system is not accepted as true? The solar system began from a spinning cloud of dust and gas. The center of the early solar system was so hot, only rocky planets were able to sustain the heat. Gravity pulled clumps of dust and gas together which eventually formed the planets. The sun began as a large rocky planet, but as clumps of matter kept getting pulled toward it by gravity, it became much larger and hotter.
- 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.
