Explanation
  • Sunspots are darkish, planet-sized regions that seem on the "floor" of the sun. Sunspots are "darkish" because they're cooler than their environment.
  • A big sunspot would possibly have a critical temperature of 4,000 ok (about three,seven hundred° C or 6,seven hundred° F), tons lower than the five,800 ok (about five,500° C or 10,000° F) temperature of the adjacent photosphere.
  • Sunspots are most effective darkish in evaluation to the bright face of the sun. If you may reduce a median sunspot out of the sun and place it someplace else within the night time sky, it might be about as shiny as a complete moon.
  • Sunspots have a lighter outer segment referred to as the penumbra, and a darker central area named the umbra.
