Solar System
The Solar System consists of the Sun and everything that orbits around it, including planets, dwarf planets, moons, asteroids, comets, and meteoroids, all bound together by gravity.
At the center is our Sun, a G-type main-sequence star that accounts for about 99.86% of the Solar System's total mass.
The four inner, rocky planets (Mercury, Venus, Earth, and Mars) are followed by the asteroid belt, and then the four gas giants (Jupiter, Saturn, Uranus, and Neptune).
Beyond Neptune lies the Kuiper Belt, home to many icy bodies including Pluto, and even farther out is the hypothetical Oort Cloud, the source of long-period comets.
The Solar System is located in the Orion Arm of the Milky Way galaxy, about 27,000 light-years from the galactic center, and completes one orbit around it every 230 million years.
