Planet Formation : Planet Formación
Planet formation begins with a collapsing cloud of dust and gas within a nebula. As the materials in in the cloud get closer together, the center gets hotter and more compressed. Motion within the collapsing cloud causes it to rotate. As the cloud becomes more and more compressed, all the materials begin to rotate in the same direction. The cloud will eventually flatten into a disk and will get thinner as it continues to spin. These flattened disk are called "circumstellar" or "protoplanetary" disks. They are the start of a planet.
Soon small pieces rotating in the disk will sweep up near material and grow bigger and bigger like rolling a snow ball. The bigger the disk gets, the more material it will attract. In this stage we call the growing material planetesimals. As the planetesimals get bigger, it starts to clear a path around it while gathering rubble and gas. Lots of these planetesimals form at the same time and if they are close enough CRASH they can send debris flying. However, if they slowly move towards each other gravity can draw them into a union and form an even larger object.
The Hubble Space Telescope provided pictures of space and the information from those pictures was used to create the theory of planetary formation.
