NGSS.HS-ESS1-4

One of the earliest models of solar formation, in which a large cloud of gas began to collapse in under its own gravity to form the Sun and planets.

• Condensation theory

• Core-accretion theory

• Nebular theory

• Gravitational Instability theory

These are the four innermost, rocky planets.

• Jovian planets

• terrestrial planets

• planetesimals

• plutinos

The four outermost planets, they are gas giants.

• Jovian planets

• Terrestrial planets

• Planetesimals

• Plutinos

The gradual growth of bodies, such as planets, by the accumulation of other smaller bodies. Aka: "snowballing"

• Fragmentation

• Accretion

• Density

• Gravitational Instability

The currently favored model of solar system formation.

• Condensation Theory

• Core-accretion Theory

• Nebular Theory

• Selection effect

• Comparative Planetology

This is the swirling gas surrounding the early Sun during the epoch of solar system formation.

• Solar nebula

• Hot Jupiter

• Condensation Nuclei

• Plutinos
