Understanding What sparked the birth of our solar system?
Gravity caused the cloud to collapse, forming the Sun at the centre while remaining material formed planets, moons, asteroids, and comets.
A deeper explanation
The Solar System's structure reflects the conditions present during its formation. The inner planets became rocky because temperatures near the Sun prevented lighter materials from remaining, while outer planets accumulated gases and ice.
