Where the star came from?

Answer 1

Scientists believe that the Sun and our solar system formed at nearly the same time out of the solar nebula - an enriched interstellar gas and dust cloud that existed where our solar system now lives. The theorized order of events for the birth of our Sun is similar to what we see in newly forming stars today. Compression from nearby disturbances causes the interstellar medium to collapse. Small clumps of gas and dust break away from the larger cloud. These denser knots have gravity and begin to gather other gas and dust around them. Temperatures begin to rise due to the further increase in gravity from material in the collapsing gas cloud. The center of this fragmented gas cloud evolves quickly (over the next 100,000 years) to form a protostar and once pressure and temperatures reach a peak, nuclear fusion begins.
