Protoplanet Hypothesis 5 billion years ago a clod of dust and gas 10 billion km in diameter rotated. As time passed the cloud shrank under its own gravity, or collapsed from an explosion. Shrinking made the cloud spin faster. The spinning made the cloud compress. The compression formed a hydrogen fusion or our sun. The rest of the dust and gas compressed into planets
FISSION THEORY 1.The sun bursts open. 2.The planets shoot out of the sun and go to their places. Then they start to orbit around the sun. 3.The moon then lifted out of the Pacific ocean on a high tide. It then started to orbit around the world.
Capture Theory Moons and planets were circling around the solar system. The suns gravitational pull captured some of them.
ACCRETION THEORY 2 Piles of rock and dust were forced together to form the earth and the moon. They got too close to each other and started to orbit.
PLANETARY COLLISION THEORY The earth collides with another planet. The collision caused an explosion that threw rocks into space. The rocks became our moon and started to orbit us. http://atropos.as.arizona.edu/aiz/teaching/nats102/ mario/images/Moon_formation_collision.mov
STELLAR COLLISION THEORY The planets, moons, and sun in our solar system were spun of from a collision between 2 stars
GAS CLOUD THEORY Clouds of gas were created by the sun. The clouds moved away from the sun and started to spin and push themselves together to form our planets.
