Answer details
Central Star
The Sun is the central star of the system, containing more than 99 percent of its total mass and exerting the gravitational force that keeps all other bodies in orbit.
Planetary Structure
There are eight recognized planets: the inner terrestrial planets (Mercury, Venus, Earth, and Mars) and the outer giant planets (Jupiter, Saturn, Uranus, and Neptune).
Other Celestial Bodies
The system includes five officially named dwarf planets, such as Pluto, along with hundreds of moons and millions of smaller bodies like asteroids, comets, and meteoroids.
Galactic Location
The solar system is located in the Orion Arm of the Milky Way galaxy and orbits the galactic center approximately every 230 million years.

Solar System
The Solar System is the gravitationally bound system of the Sun and the masses that orbit it, most prominently its eight planets, of which Earth is one. The Solar System is an isolated single-star planetary system (not part of a larger star system) within the Milky Way Galaxy. The system formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, creating the Sun and a protoplanetary disc from which the orbiting bodies
