French philosopher and mathematician René Descartes was the first to propose a model for the origin of the Solar System in his book The World, written from 1629 to 1633.. In his view, the universe was filled with vortices of swirling particles, and both the Sun and planets had condensed from a large vortex that had contracted, which he thought could explain the circular motion of the plane
~ 50 million years before formation of the Solar System 4.6 bya: If the Solar System formed in an Orion Nebula-like star-forming region, the most massive stars are formed, live their lives, die, and explode in supernova. One particular supernova, called the primal supernova, possibly triggers the formation of the Solar System. [19] [20 ...
This distant formation offers a potential explanation for Jupiter's enrichment in noble gases. [19] [20] However, dedicated formation models indicate that it is difficult to reconcile growth via pebble accretion with the final mass and composition of the solar system ice giants Uranus and Neptune. [21] [22]
The Solar System remains in a relatively stable, slowly evolving state by following isolated, gravitationally bound orbits around the Sun. [28] Although the Solar System has been fairly stable for billions of years, it is technically chaotic, and may eventually be disrupted. There is a small chance that another star will pass through the Solar ...
1796 – Pierre Laplace re-states the nebular hypothesis for the formation of the Solar System from a spinning nebula of gas and dust. [ 124 ] 1798 – Henry Cavendish accurately measures the gravitational constant in the laboratory , which allows the mass of the Earth to be derived, and hence the masses of all bodies in the Solar System.
The standard model for the formation of the Solar System (including the Earth) is the solar nebula hypothesis. [22] In this model, the Solar System formed from a large, rotating cloud of interstellar dust and gas called the solar nebula.
In the inner Solar System, chondrules appear to have been crucial for initiating accretion. [35] The tiny mass of asteroids may be partly due to inefficient chondrule formation beyond 2 AU, or less-efficient delivery of chondrules from near the protostar. [35]
The Solar System belts were formed in the formation and evolution of the Solar System. [6] [7] The Grand tack hypothesis is a model of the unique placement of the giant planets and the Solar System belts. [3] [4] [8] Most giant planets found outside our Solar System, exoplanets, are inside the snow line, and are called Hot Jupiters.
