Detailed explanation-1: -Answer: C. The sun and planets formed from a collapsing spinning cloud of gas and dust. Explanation: The entire solar system was formed from solar nebula.
Detailed explanation-2: -1 Answer. Kepler’s law of planetary motion and Newtons laws of motion are sufficient to explain the observed data of planetary motion.
Detailed explanation-3: -Which explanation of the solar system best fits the observations of the planets and how they began orbiting the sun? The gravity of a large, massive star passing the sun ripped off blobs of material from it that formed the planets.
Detailed explanation-4: -The most widely accepted explanation of how the solar system formed is called the nebular hypothesis. According to this hypothesis, the Sun and the planets of our solar system formed about 4.6 billion years ago from the collapse of a giant cloud of gas and dust, called a nebula.
Detailed explanation-5: -The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
