<–this is
the most detailed picture of a sunspot (yes, I guess there are a few up there now) ever taken. It’s from the Big Bear Observatory on Big Bear Lake at an elevation of 6700 feet in California. The sunspot is about as big as the Earth (it would take about 110 Earths to go across the diameter of the sun one time). The temperature of the middle of the sunspot is about 6500F, while the surrounding area is at about 10,400F. We have been in an extended period of minimal sunspot activity for the last several years. The Earth moves in orbit around the sun at a speed of approximately 67,000 mph. The sun is closest to the Earth in the first week of January and farthest away in the first week of July. The sun is actually slightly bigger and brighter in the Northern Hemisphere winter than in the summer.
