How was the sun formed step by step for kids?

2023 Jan 19

The Sun formed about 4.6 billion years ago from a cloud of gas and dust. Here are the main steps:

  • A huge cloud of gas and dust, called a nebula, began to collapse under its own gravity.
  • As the cloud collapsed, it began to spin and flatten into a disk shape.
  • In the center of the disk, the gas and dust became so dense and hot that nuclear fusion began, and the Sun was formed.
  • The leftover gas and dust in the disk began to clump together to form planets, like Earth.
  • The solar wind from the sun was blowing out the remaining gas and dust around it, forming the solar system.

That’s a brief overview of how the Sun formed!
