6 steps of solar system formation

Step 1: 5 billion years ago the sun formed from a cloud of gas and dust that collapsed because of gravity

step 2: after the cloud collapsed it formed into a rotating disk. very dense and hot in the center where the star began to form

step 3: the spinning motion of the disk caused it to flatten. planetesimals formed causing more changes to the disk

step 4: as the planetesimals grew their gravitational pull increased and the large planetesimals collected more of the gas and dust

step 5: small planetesimals collided with larger ones and the planets began to grow larger and more stable

step 6: each planet swept up the material in its region so the planetary orbits are separate from each other

This would be an open primary. a closed primary people can vote only prior to election day if the party if they are registered. independent voters can not participate. there is not a wide-open primary, but there is a semi-open primary.
