  2. Formation and evolution of the Solar System - Wikipedia

    en.wikipedia.org/wiki/Formation_and_evolution_of...

    ~ 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 ...

  3. Timeline of Solar System astronomy - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_Solar_System...

    1796 – Pierre Laplace re-states the nebular hypothesis for the formation of the Solar System from a spinning nebula of gas and dust. [125] 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. [126]

  4. History of Solar System formation and evolution hypotheses

    en.wikipedia.org/wiki/History_of_Solar_System...

    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.

  5. Solar System - Wikipedia

    en.wikipedia.org/wiki/Solar_System

    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 ...

    This time happens to correspond roughly to the time of the formation of the Solar System and the evolutionary history of life. Stelliferous Era: 150 Ma ~ 100 Ta [16] 20 ~ −0.99: 60 K ~ 0.03 K: The time between the first formation of Population III stars until the cessation of star formation, leaving all stars in the form of degenerate ...

  7. Nebular hypothesis - Wikipedia

    en.wikipedia.org/wiki/Nebular_hypothesis

    The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets.

  9. Timeline of discovery of Solar System planets and their moons

    en.wikipedia.org/wiki/Timeline_of_discovery_of...

    The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
