|
it was just made
|
|
|
gravity pushed all of the dust into each other and made the sun then the sun made the earth
|
|
|
Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula

|
|
the sun attracted the dust to form planets

Detailed explanation-1: -Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.
Detailed explanation-2: -When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
Detailed explanation-3: -About 4.6 billion years ago, an enormous cloud of hydrogen gas and dust collapsed under its own weight, eventually flattening into a disk called the solar nebula.
Detailed explanation-4: -The evolving Solar System assumes a flat, disk shape of condensing gases and dust with the Proto Sun (or pre Sun) at the center. The consolidation of matter under gravitational attraction causes the surrounding nebular cloud to flatten and spin.
