Arrange the correct sequence of the formation of the solar system. Use the image as your guide.

• As the planets grew, their gravity was strong enough to hold hydrogen and helium, forming giant gas planets.

• Formation of the solar system occurred as the force of gravity began to pull materials in the cloud. Most of the material was pulled to the center. As it became tightly packed, it got hotter and the pressure on it increased.

• The bodies that formed in this region were comparatively low in mass and were too weak to hold onto the light gases such as hydrogen and helium.

• Once nuclear fusion began, the sun gave off light and became a stable star.
