1553 - What does the solar nebular hypothesis explain about the origin and formation of the solar system?

The solar nebular hypothesis explains how our solar system was formed about 4.6 billion years ago. It says that a huge cloud of gas and dust called a nebula was floating in space.

This nebula started to spin faster and faster, and as it did, it began to flatten out into a disk shape with the sun in the middle.

The gas and dust in the disk cooled down and turned into small particles that stuck together to form rocks. These rocks kept sticking together to form bigger objects like planets, moons, and asteroids.

Eventually, after millions of years, our solar system was formed with the sun at the center and eight planets (Mercury to Neptune) and other objects like moons and asteroids orbiting around it.
