4 More Charts(:

5 Videos **These are videos of sun storms and they form auroras which make really pretty colors.

6 Did You Know.?? Light from the sun reaches Earth in eight minutes The sun is the closest star to Earth The sun is already halfway through it’s lifetime 109 planet earths would fit on Earth’s surface but guess what it’s even cooler?? MORE THAN ONE MILLION earths would fit inside..! Every 11 years the sun reverses its magnetic polarity.(it’s south pole becomes it north and it’s south pole becomes it’s north). Solar flares burst and sometimes knock out our electricity.!! No solar eclipse can last more than 7 minutes and 58 seconds

7 (:*The Sun* The sun is extremely hot, it can reach up to 22.5 million degrees at it’s core.!! The sun moves around the earth at 15 degrees per hour. At the poles the sun goes around in circles above or below the horizon. 55% of humans do not know that the sun is in fact, a star. Most stars are only visible at night but…our sun is visible throughout the day. Sun spots are simply cooler regions on the suns surface. It’s mean distance from earth is one astronomical unit.

8 ..!-My Only Sunshine!..-

9 **More About the Sun(: The diameter of the sun is 1,390,000 km The mass is 1,989,030 kg The temperature of the sun is 15,600,000 k and 9,900 f on the surface The element helium was named after the sun. The sun is about 70% hydrogen and 28% helium, the other 2% is metals. Solar winds travel through the solar system at 450 km/sec. The Northern Lights are caused by the sun’s flares. The sun is middle ager it is around four and a half million years ago.

10 *Last Slide of Facts I promise.!!(: The sun is a medium sized yellow star that is 93,026,724 miles away from earth (also known as one astronomical unit). The sun’s absolute magnitude is +4.83. It’s stellar type is G. The sun is also called “Helios” by the Romans and “Sol” by the Greeks. The sun is closest to earth on January 2 each year and farthest away on July 2 each year. Our sun is a second generation star which means it burns other gasses rather than just helium.
