| Sun Fact Sheet |
Astronomy ---------------- Composition |
| The Sun is a G2 type star. It's surface is called the photosphere. Outside the photosphere is the chromosphere. The sun's brilliancy is expected to increase by 10% in the over the next 1.1 billion years. |
| The sun travels at a speed of 155 miles per second, but it still takes 230 million years for it to complete a single revolution of the galaxy. The sun’s equator is 2,717,952 miles around. It takes roughly 25.38 days for the visible photosphere and the convection zone just below it to make a complete revolution at the equator at about 4,400 miles per hour, but about 36 days near the poles at 545 miles per hour. The biggest sun flares are equivalent to billions of megatons of TNT, all on a timescale of 10 to a thousand seconds. The fourth largest sun flare on record was captured by SOHO's Extreme Ultraviolet Imaging Telescope on October 28, 2003. The sun will shrink into a white dwarf. Light from the sun reaches the Eath 499.004782 seconds ago. |
