The Sun is Earth’s nearest star. The Sun is a ball of gas that is so hot that it glows, giving off light.	Diameter: 865,000 miles (1,392,000 km) Distance from Earth: 93,000,000 miles (150,000,000 km) Distance from Moon: 92,761,140 miles (149,615,600 km)	The surface temperature of the Sun is 11,000 degrees F. The temperature at the center is 27 million degrees F.
The Sun rotates on its axis about once every 25 days.		The Sun is so large that a million Earths could fit inside the Sun.
The Sun’s energy is produced from nuclear fusion reactions. Hydrogen atoms combine to form helium in the core.		The Sun is in the middle of its lifetime and has about 5 billion more years before it burns itself out.
The Sun was born about 5 billion years ago from a large dark gas cloud in the Milky Way. The planets were formed at the same time. Light travels at a speed of 300,000km per second. At this speed, Sunlight takes 8 1/2 minutes to reach Earth. Without the Sun’s warmth and light, the Earth would be an icy rock without life. How Much Do You Know About Our Moon?
