The Sun is the star at the center of the Solar System. |
It has a diameter of about 1,392,000 km, about 109 times that of Earth, and its mass (about 2×10 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of theSolar System. |
Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium. The Sun's hot corona continuously expands in space creating the solar wind, a stream of charged particles that extends to the heliopause at roughly 100 astronomical units. The energy of this sunlight supports almost all life on Earth by photosynthesis, and drives Earth's climate and weather. The Sun's magnetic field leads to many effects that are collectively called solar activity, including sunspots on the surface of the Sun, solar flares, and variations in solar wind that carry material through the Solar System.
