Pre-solar nebula[ edit ] The nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud. This indicates that one or more supernovae occurred near the Sun while it was forming. A shock wave from a supernova may have triggered the formation of the Sun by creating relatively dense regions within the cloud, causing these regions to collapse. This cluster began to break apart between million and million years after formation. As the material within the nebula condensed, the atoms within it began to collide with increasing frequency, converting their kinetic energy into heat. The centre, where most of the mass collected, became increasingly hotter than the surrounding disc.

Uranus and Neptune are sometimes referred to as failed cores. At the current locations it would have taken millions of years for their cores to accrete.

From that a minimum mass of the nebula i. It was derived that the nebula mass must have exceeded times that of the Earth. However, this has been questioned during the last 20 years.

Currently, many planetary scientists think that the Solar System might have looked very different after its initial formation: several objects at least as massive as Mercury were present in the inner Solar System, the outer Solar System was much more compact than it is now, and the Kuiper belt was much closer to the Sun. These objects would have gravitationally interacted with one another, tugging at each other's orbits until they collided, growing larger until the four terrestrial planets we know today took shape.

The " gravitational drag " of this residual gas would have eventually lowered the planets' energy, smoothing out their orbits. As the large bodies moved through the crowd of smaller objects, the smaller objects, attracted by the larger planets' gravity, formed a region of higher density, a "gravitational wake", in the larger objects' path.

As they did so, the increased gravity of the wake slowed the larger objects down into more regular orbits. The asteroid belt initially contained more than enough matter to form 2—3 Earth-like planets, and, indeed, a large number of planetesimals formed there. Jupiter's gravity increased the velocity of objects within these resonances, causing them to shatter upon collision with other bodies, rather than accrete.

Because the frost line accumulated large amounts of water via evaporation from infalling icy material, it created a region of lower pressure that increased the speed of orbiting dust particles and halted their motion toward the Sun. Uranus and Neptune are thought to have formed after Jupiter and Saturn did, when the strong solar wind had blown away much of the disc material.
