The system composed of the sun and the celestial bodies moving around it and its occupancy space area. The celestial body system composed of the sun, planets and their satellites and rings, asteroids, comets, meteoroids and interplanetary materials and the space area they occupy.

The Solar System is the star system we are in now. It is centered on the sun and a collection of all celestial bodies bound by the sun's gravity: 8 planets Pluto has been expelled, at least 165 known satellites, and hundreds of millions of small solar system objects.

Once the young Sun began producing energy, the solar wind blew material from the protoplanetary disk into interplanetary space, ending planetary growth. Young T Tauri stars have much stronger stellar winds than older stars in a stable phase.

According to astronomers' speculation, the current solar system will remain until the sun leaves the main sequence. Since the sun uses the hydrogen inside it as fuel, in order to use the remaining fuel, the sun will become hotter and hotter, so it will burn faster and faster. This causes the sun to continue to brighten, at a rate of approximately 10% every 1.1 billion years.

About 7.6 billion years from now, the Sun's core will be hot enough to fuse the outer layers of hydrogen, which will cause the Sun to expand to 260 times its current radius and become a red giant. At this time, due to the expansion of volume and surface area, the total luminosity of the sun increases, but the surface temperature decreases and the luminosity per unit area becomes darker.
