The Big Bang
how planets form in simple terms.
planet formation
astronomers have wondered for a long time about how our planets formed even with advances in the distance a telescope can see all that we could see was the end result.
Internal movement within the collapsing cloud cause it to churn then as the cloud gets compressed much of the cloud begins rotating in the same direction. the rotating cloud gets flattened and turns into a disk (like in the picture above) that gets thinner as it spins. These "protoplanetary" or "circumstellar" disks as astronomers call them are the birthplacs of planets. As a disk spins , the material within it will travel around with it. Eventually the material with it will begin to stick to other materials. The bigger these clumps of material get the more they begin to suck in. In the inner part of the disk it begins to become rocky because most of the gas that made it has been taken already by the star but there is ice and gases on the outer rim of the disk which hasn't been destroyed or used by the growing star yet which will let other smaller almost planets use to get bigger in size. As each planetestimal gets bigger it will you know take in more material at a faster rate. with hundreds of planetestimals forming they are bound to collide and form together (by the way planetestimals are young almost planets). eventually the planetestimals will have a clear path with no debris in its way. After millions of years of colliding planetestimals they eventually become planets.
