Ideas concerning the origin and fate of the world date from the earliest known writings; however, for almost all of that time, there was no attempt to link such theories to the existence of a "Solar System", simply because it was not generally thought that the Solar System, in the sense we now understand it, existed. The first step toward a theory of Solar System formation and evolutio.

About us.
This is how Jupiter, Saturn, Uranus and Neptune, the gas giants of our solar system, are thought to have formed. Jupiter and Saturn are thought to have formed first and quickly within the first 10 million years of the solar system. In the warmer parts of the disk, closer to the star, rocky planets begin to form.
These colder regions also allow gas molecules to slow down enough to be drawn onto a planet. This is how Jupiter, Saturn, Uranus and Neptune, the gas giants of our solar system, are thought to have formed. Jupiter and Saturn are thought to have formed first and quickly within the first 10 million years of the solar system.
Scientists think planets, including the ones in our solar system, likely start off as grains of dust smaller than the width of a human hair. They emerge from the giant, donut-shaped disk of gas and dust that circles young stars. Gravity and other forces cause material within the disk to collide.
3 days ago· It could be that our own Sun''s disk lasted much longer than average, and therefore the planets in our solar system had a much longer period of time during which to form. "Models suggest that core accretion seems to need at least several million years to form Jupiter," says Boss, "yet most protoplanetary disks do not seem to exist that long.
Artist''s conception of a protoplanetary disk. There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. [1] Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other

This solar system, with its star, its classical planets, its dwarf planets, and its "leftover" comets and asteroids, formed from a nebula full of elements in the form of gas and dust.
