How did the solar system form according to the nebular theory?

According to the nebular theory, the solar system was formed when a huge cloud of gas and dust slowly collapsed under its own gravity. This process caused the cloud to fragment into smaller and smaller pieces, which eventually became planets and other objects in our solar system.

There are several pieces of evidence that support this theory. For example:

- The sun is located in the middle of the solar system, which is exactly where it should be according to the theory.

- The planets all orbit around the sun in the same direction, also supporting the idea that they formed from one large cloud.

- Many moons in our solar system have very similar orbits to their respective planets, again supporting the nebular theory.

The solar system is believed to have formed from the gravitational collapse of a giant molecular cloud. This theory, called the nebular theory, was first proposed in 1755 by Immanuel Kant. The nebular theory is supported by several pieces of evidence, including the observed motion of planets and comets, and the fact that many planets orbit in the same plane.

According to the nebular theory, a disk-shaped cloud of gas and dust began to rotate around its center of gravity. This rotation caused the cloud to flatten into a disk. The material in the center of the disk became more dense, while the material on the edge became less dense. This difference in density caused the disk to spin faster and faster.

As it spun, centrifugal force caused some of the material in the disk to fly outwards. This material formed a ring around the center of the disk. The rest of the material continued to spin inward, until it reachedthe centerof gravity and collapsed into a planet.The planet then began to spin, and the process repeated itself, creating a system of planets and moons.

The nebular theory is the most widely accepted explanation for the formation of the solar system. It is supported by evidence from astronomy, including the observed motion of planets and comets, and the fact that many planets orbit in the same plane.

Nebular theory is a hypothesis that proposes that the solar system formed from the gravitational collapse of a giant interstellar cloud of gas and dust. According to this theory, the sun was formed from the contraction of the central nebula and the planets were formed from the accretion of smaller particles around the sun. This theory has been supported by observations made by astronomers using telescopes and spacecraft.
