Saturn - Wikipedia
It has an eighth of the average density of Earth, but is over 95 times more massive. Even though Saturn is almost as big as Jupiter, Saturn has less than a third of its mass. Saturn orbits the Sun at a distance of 9.59 AU (1,434 million km), with an orbital period of 29.45 years.
Saturn: Facts - NASA Science
Saturn took shape when the rest of the solar system formed about 4.5 billion years ago when gravity pulled swirling gas and dust in to become this gas giant. About 4 billion years ago, Saturn settled into its current position in the outer solar system, where it is the sixth planet from the Sun.
How Saturn Formed — The Birth of the Ringed Planet
Saturn formed about 4.5 billion years ago, at the same time as the rest of the solar system, from a giant swirling cloud of gas and dust called the solar nebula.
The Origin and Evolution of Saturn, with Exoplanet Perspective
giant planets formed in this way may have super-solar metallicities but lack a heavy element core unless (as seems unlikely) very large (Earth-sized) planets are consumed by these objects.
The Origin and Evolution of Saturn: A Post-Cassini Perspective
The Saturn System has been studied in detail by the Cassini-Huygens Mission. A major thrust of those investigations has been to understand how Saturn formed and evolved and to place Saturn in the context of other gas giants and planetary systems in general.
Origin and evolution of the Saturn system - NASA Technical Reports ...
As was the case for Jupiter, Saturn formed either as a result of a gas instability within the solar nebula or the accretion of a solid core that induced an instability within the surrounding solar nebula.
The Origin And Evolution Of Saturn: A Post-Cassini Perspective
A major thrust of those investigations has been to understand how Saturn formed and evolved and to place Saturn in the context of other gas giants and planetary systems in general.
The Origin and Evolution of Saturn: A Post-Cassini Perspective
Two models have been proposed for the formation of the giant planets – the core accretion model and the disk instability model. Saturn’s heavy element enrichment, core size, internal structure, etc. compared to Jupiter strongly favors the core accretion model as for Jupiter.
Saturn planet | Canadian Space Agency
Our Sun was born at its centre, and the planets were created about 4.5 billion years ago from particles sticking together along rings in the disc. Saturn is best known for its impressive rings, which are about 20 metres thick on average.
RAPID FORMATION OF SATURN AFTER JUPITER COMPLETION
Therefore, the rapid formation of Saturn induced by gap opening of Jupiter can account for the formation of multiple gas giants (Jupiter and Saturn) without significant inward migration and larger core mass of Saturn than that of Jupiter.
