sun :
The star around which the Earth and the other planets, moons, asteroids, and all the other members of the solar system revolve. The sun is the brightest celestial object and supplies the Earth with heat and light. The sun is a ball of boiling hot gases, mainly hydrogen and helium, with a temperature of millions of degrees at its core. It is like an endless hydrogen bomb explosion with enough fuel to continue shining for another 5 billion years. About 93 million miles (149 million kilometers) from the Earth, the sun is approximately 865,000 miles (1.4 million kilometers) across. That is nearly 600 times bigger than all the planets in the solar system put together. Also, any star like the sun. The other stars seem so much dimmer that the sun because they are so much farther away.
