  2. 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 ...

  3. 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.

    The Solar System travels alone through the Milky Way in a circular orbit approximately 30,000 light years from the Galactic Center. Its speed is about 220 km/s. The period required for the Solar System to complete one revolution around the Galactic Center, the galactic year, is in the range of 220–250 million years. Since its formation, the ...

    The seven largest natural satellites in the Solar System (those bigger than 2,500 km across) are Jupiter's Galilean moons (Ganymede, Callisto, Io, and Europa), Saturn's moon Titan, Earth's moon, and Neptune's captured natural satellite Triton. Triton, the smallest of these, has more mass than all smaller natural satellites together.

  7. Solar System belts - Wikipedia

    en.wikipedia.org/wiki/Solar_System_belts

    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.

  8. Planetary science - Wikipedia

    en.wikipedia.org/wiki/Planetary_science

    The Solar System has now been relatively well-studied, and a good overall understanding of the formation and evolution of this planetary system exists. However, there are large numbers of unsolved questions, [ 4 ] and the rate of new discoveries is very high, partly due to the large number of interplanetary spacecraft currently exploring the ...

  9. Discovery and exploration of the Solar System - Wikipedia

    en.wikipedia.org/wiki/Discovery_and_exploration...

    The Solar System is one of many planetary systems in the galaxy. [1] [2] The planetary system that contains Earth is named the "Solar" System. The word "solar" is derived from the Latin word for Sun, Sol (genitive Solis). Anything related to the Sun is called "solar": for example, stellar wind from the Sun is called solar wind.
