Pre-Solar System Billions of years before the formation of the Solar System Over 4.6 billion years ago (bya) Previous generations of stars live and die, injecting heavy elements into the interstellar medium out of which the Solar System formed. [15] ~ 50 million years before formation of the Solar System 4.6 bya
The thin disk of our galaxy began to form when the universe was about 5 billion years old or 9 ± 2 Gya. [15] The Solar System formed at about 9.2 billion years (4.6 Gya), [5]: 22.2.3 with the earliest evidence of life on Earth emerging by about 10 billion years (3.8 Gya).
This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years. Many stars, including the Sun, were formed within this collapsing cloud. The gas that formed the Solar System was slightly more massive than the Sun itself.
The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.
11.8 billion years (2 Gya): Olympus Mons, the largest volcano in the Solar System, is formed; 12.1 billion years (1.7 Gya): Sagittarius Dwarf Spheroidal Galaxy captured into an orbit around Milky Way Galaxy; 12.7 billion years (1.1 Gya): Copernican Period begins on Moon: defined by impact craters that possess bright optically immature ray systems
Using numerical simulations, the researchers figured out that a flyby like this would have about a 1 in 100 chance at reshaping our Solar System into what it is today, and that the interloping ...
The result of this process, which lasts for 10 to 100 million years, is the formation of a limited number of Earth-sized bodies. Simulations show that the number of surviving planets is on average from 2 to 5. [2] [21] [62] [66] In the Solar System they may be represented by Earth and Venus. [21]
