Detailed explanation-1: -The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12].
Detailed explanation-2: -There are many pieces of evidence that support the nebular hypothesis, including:-The chemical composition of the Sun and planets is similar to that of interstellar gas clouds. – PLANETS ARE OBSERVED TO FORM IN OTHER STAR SYSTEMS (Eg. Protoplanetary disks have been observed around young stars).
Detailed explanation-3: -The solar nebular hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas. It is believed that the sun, planets, moons, and asteroids were formed around the same time around 4.5 billion years ago from a nebula.
Detailed explanation-4: -The nebular hypothesis is the possible explanation for how the Sun, the Earth, and the rest of the solar system formed approximately 4.6 billion years ago out of the gravitational collapse of a large cloud of gas and dust left behind from previous star formation and star life cycles.
Detailed explanation-5: -Answer and Explanation: The various nebulae that astronomers can directly see with telescopes provides evidence for the nebular theory.
