how the sun formed???
Answers
This is the widely accepted theory on how the sun was formed.
From other stars, astronomers found that the sun most likely started out as a large collapsing cloud of gas inside some interstellar clout.
The cloud collapsed for millions of years, until it formed a rotating disk with a large central bulge. You know, something like this:
Pretty neat huh? And inside the rotating disk, bits of matter will eventually collide and begin to form our planets. And one of those planets will be Earth!
The central bulge repeatedly collapsing under its own gravity until the temperatures in the core got so high that deuterium atoms (an isotope of hydrogen) began to fuse and give off thermonuclear energy. This caused the continuous collapse to slow down and eventually led the sun to its second stage; where Hydrogen nuclei begin to fuse into Helium. This is what started the sun’s current evolutionary phase.
