The Sun (Sun) is the central object of the solar system, accounting for 99.86% of the total mass of the solar system. The eight planets, asteroids, meteors, comets, outer Neptunian objects, and interstellar dust in our solar system all revolve around the Sun, which in turn revolves around the center of the Milky Way.
The Sun is the star at the center of our solar system, and it is almost an ideal sphere of hot plasma intertwined with a magnetic field. The diameter of the Sun is about 1392000 (1.392×10⁶) kilometers, which is 109 times the diameter of the Earth; its volume is about 1.3 million times that of the Earth; and its mass is about 2×10³⁰ kg (330,000 times that of the Earth). In terms of chemical composition, about three-quarters of the Sun’s mass is now hydrogen, with almost all the rest being helium, including less than 2% of the mass of oxygen, carbon, neon, iron and other heavy elements, using nuclear fusion to release light and heat into space.
The Sun is currently traversing a local interstellar cloud in the local bubble of the Orion Arm at the inner edge of the Milky Way. There are 50 nearest star systems at a distance of 17 light-years from Earth (the closest star to the Sun is a red dwarf called Proxima, about 4.2 light-years away).
