### Physical Properties

The solar diameter equals 109 Earth diameters, or 1,390,000 kilometers. What we see when we look at the sun, however, is not a solid, luminous surface, but a spherical layer, called the photosphere, from which the bulk of the solar light comes from. Above the photosphere the solar atmosphere is transparent, allowing light to escape. Below the photosphere, the physical conditions of the material of the solar interior prevent light from escaping. As a result, we cannot observe this interior region from the outside. The solar mass is equivalent to 330,000 earth masses.

### Properties of the sun

• The Sun’s surface is called the photosphere.  The temperature of the photosphere is about 10,000 Fahrenheit.  Its core is under its atmosphere. The temperature at the core, or very middle, of the Sun, is about 27 million Fahrenheit.

•     The Sun’s diameter is about 870,000 miles wide.  The Sun is 109 times wider than Earth, and is 333,000 times heavier.  That means if you put the Sun on a scale, you would need 333,000 objects that weigh as much as the Earth on the other side to make it balance.

### What is it made out of

• The sun is a big ball of hot gases. The gases are converted into energy in the sun's core. The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light. Most of the gas — about 72 percent — is hydrogen. Nuclear fusion converts hydrogen into other elements. The sun is also composed of about 26 percent helium and trace amounts of other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon.

• These elements are created in the sun's core, which makes up 25 percent of the sun. Gravitational forces create tremendous pressure and temperatures in the core. The sun in this layer is about 27 million degrees F (15 million degrees C). Hydrogen atoms are compressed and fuse together, creating helium and a lot of energy. This process is called nuclear fusion

### What is it made out of (part 2)

• These elements are created in the sun's core, which makes up 25 percent of the sun. Gravitational forces create tremendous pressure and temperatures in the core. The sun in this layer is about 27 million degrees F (15 million degrees C). Hydrogen atoms are compressed and fuse together, creating helium and a lot of energy. This process is called nuclear fusion.
