The solar system is a gravitationally bound system comprising the Sun—a G2V-type star—and all celestial objects that orbit it, formed approximately 4.6 billion years ago from a massive, collapsing interstellar gas and dust cloud. Located in the Milky Way galaxy’s Orion-Cygnus Arm, it contains eight recognized planets divided into four inner rocky terrestrial worlds (Mercury, Venus, Earth, Mars) and four outer giant planets (Jupiter, Saturn, Uranus, Neptune). 

The system is defined by the Sun’s immense gravity, which anchors planets, at least 150 known moons, asteroids, and comets in elliptical paths. Beyond the planets lies a vast, icy region containing dwarf planets like Pluto and the Oort cloud. The system revolves around the galactic center at roughly 515,000 mph, with the Sun providing necessary energy for life, particularly on Earth.
