SOLAR SYSTEM

Detailed explanation-1: -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.

Detailed explanation-2: -What came out of the evolutionary hypothesis was the solar nebula theory, the theory that posits that the planets and sun in the solar system formed from the solar nebula. The solar nebula is a cloud of interstellar gas and dust that condensed to form the entire solar system, including the sun and planets.

Detailed explanation-3: -The nebular theory states that our solar system formed from the gravitational collapse of a giant interstellar gas cloud-the solar nebula.

Detailed explanation-4: -Some scientists think the supernova shock wave triggered the collapse of the gas and dust cloud. Others disagree, suggesting that radiation emitted by a nearby star might have been enough to collapse the cloud, which led to the birth of the Sun, planets, and, eventually, all life on Earth.

Detailed explanation-5: -Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together.
