Solar Nebula Disperses


Solar Nebula Disperses

The growing proto-Sun accumulated much of the original material from the nebula long before planets formed. A small portion was incorporated into the planets, but the remainder was swept away when increasing temperatures and pressures initiated nuclear reactions in our Sun's core. The force of the reaction caused a strong solar wind to expel the outer layers of the Sun into space beyond our solar system. A much weaker solar wind continues to flow from our Sun today.
