The
sun is an incredible thing. The sun is our local star, and a big
ball of gas.
Earth receives about one two-billionths of the energy
radiating 4x1033ergs per second. The sun is 865, 000
miles across, about 109 times the size of Earth. it is about 93
million miles distant, and 107 similar suns could fit between it and the
orbit of Earth. The sun rotates counterclockwise, the equatorial
regions having a period of about 26 days, the polar regions about 37
days. At the core the temperature is about 15 million degrees
Kelvin, and the density of the gas is eight times that of gold.
Whereas the photosphere is at about 6,000 degrees Kelvin, a sunspot may be
thousands of degrees cooler. |
