Planetary systems similar to or like Solar System

Gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Wikipedia

  • Formation and evolution of the Solar System

    The formation and evolution of the Solar System began about 4.57 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other small Solar System bodies formed. Wikipedia

  • Planet

    Astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and – according to the International Astronomical Union but not all planetary scientists – has cleared its neighbouring region of planetesimals. Ancient, with ties to history, astrology, science, mythology, and religion. Wikipedia

  • Jupiter

    Fifth planet from the Sun and the largest in the Solar System. Gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. Wikipedia

  • Sun

    Star at the center of the Solar System. Nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light and infrared radiation. Wikipedia

  • Geology of solar terrestrial planets

    The geology of solar terrestrial planets mainly deals with the geological aspects of the four terrestrial planets of the Solar System – Mercury, Venus, Earth, and Mars – and one terrestrial dwarf planet: Ceres. Only terrestrial planet known to have an active hydrosphere. Wikipedia

  • List of possibly gravitationally rounded objects of the Solar System, which are objects that have a rounded, ellipsoidal shape due to their own gravity . Their sizes range from planetary-mass objects like dwarf planets and some moons to the planets and the Sun. Wikipedia
