Answer:
The Sun is a star, a yellow star on the main sequence of stellar aging. It formed about 4 to 5 billion years ago, along with all the planets, from a spinning disk of hydrogen and other elements.
The Sun is a ball of gas, almost all of which exists as a ionized plasma. It creates energy at its core by the fusion of hydrogen into helium, at an inner temperature of 13 to 15 million degrees Celsius (13M-15M K). The energy is released in the outer layer of the Sun, or photosphere, which is about 6000 °C.
Although it fuses about 700 million tons of hydrogen every second, the Sun is still predominantly hydrogen. It is about 92% hydrogen, 7% helium, and less than 1% all other elements.
The Sun is about 150 million kilometers (93 million miles) from Earth, and its sunlight takes about 8 minutes to reach Earth at 300,000 km/second. The Sun has much more mass than the rest of the solar system, equal to 332,946 Earth masses.
The Sun rotates (counter-clockwise from above) like the Earth, but at different surface speeds because it is gaseous. Depending on location, a point on the Sun's surface makes one complete rotation in from 25 to 36 days. Closer to its core, the rotation period is about 27 days.
The Sun and other stars in the galaxy rotate around the center of the Milky Way. The Sun completes one revolution around the center in about 225 million years.
