The sun is a star. It is like many other stars in the sky. But it looks bigger and brighter. This is because it is much closer to Earth than any other star. The Sun is made almost entirely of hydrogen and helium. In the Sun's core, temperatures soar to 15,000,000°C (27,000,000°F). The Sun also has several layers: the photosphere, the chromosphere, and the corona. The photosphere is the only layer people can see during normal daylight. This fiery hot layer has a temperature of 6000°C (11,000°F) and a blotchy appearance due to the turbulent eruptions of energy at the surface. The hot gases of this layer produce light by a process called incandescence. The chromosphere and corona are only visible during a solar eclipse. The chromosphere is an irregular layer above the photoshere. The most remarkable aspect of the corona is its high temperature. This outermost layer reaches about 1,000,000°C (1,800,000°F). The corona is the Sun's outer atmosphere. Sunspots are dark patches on the Sun's surface. These relatively cool areas are caused when the Sun's magnetic fields slow down the radiation of heat. Photosphere, luminous, apparently opaque layer of gases that forms the visible surface of the sun or any other star. The photosphere lies between the dense interior gases and the more attenuated gases of the chromosphere. The incandescent gases of the photosphere, estimated to be at temperatures near 6,000degK, are so much brighter than the other layers of the sun that they seem to form a surface. Another feature of the photosphere, observed only near the sun's edge, is the appearance near sunspots of bright, veinlike regions known as faculae. The sun is the center of the solar system. All the planets orbit (move in a circle) around it. The sun is about 93 million miles (150 million kilometers) from Earth. The sun is a burning ball of gases. It is much larger than Earth. About 1.3 million Earths could fit inside it. The core, or center, of the sun is very hot. This is where the sun makes its energy. It takes a long time for the energy to get from the core to the surface. After that, sunlight takes about eight minutes to reach Earth. Storms on the sun's surface are called sunspots. These areas are cooler, so they look dark. The sun also sends out explosions of energy called solar flares. People and animals need the sun to stay alive. Plants use sunlight to grow. The sun also affects the weather. Without the sun, nothing could live.They shoot out into space.
