The Solar System consists of the sun and the celestial objects bound by its gravity.

These planets include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. At one point Pluto was also considered the ninth of Sun's Solar System, until it was later defined as a moon capable of its own gravity pull. The moon also pulls the planet's 166 moons and four dwarf planets in its gravity.

When broadly describing the Solar System and its region, it is easiest to consider the solar system's largest bodies, the Sun, four terrestrial inner planets, the asteroid belt, four gas giant outer planets, the Kuiper belt, the scattered disk and the hypothetical Oort Cloud.

A solar wind permeates the Solar System, made of charged particles from the sun. This solar wind creates the heliosphere, which is separated from the rest of the solar system by the heliopause located around the scattered disk.

The sun is the main component of the Solar System, which every other part of the Solar System revolves around. The sun contains 99.86 percent of the Solar System's known mass. Jupiter and Saturn account for 90 percent of the remaining mass of the Solar System.

A large majority of the objects in the Solar System lie near Earth's orbit, which is known as ecliptic. The planets are very close to ecliptic while comets and the Kuiper belt are usually at different angles to it. The planets orbit with the Sun's rotation, which is counter clockwise, with a few exceptions such as Halley's Comet.

Every body in the Solar System varies in the distance from the sun throughout the course of its year. The closest approach to the sun is called perihelion, while the largest distance from the sun is referred to as its aphelion.
