What is the Midnight sun?
We all know that the earth rotates around the sun, but it is the earths inclination that gives us the seasons we know.

The drafts show the midnight sun on the northern pole and the dark wintertime on south pole. The polar circle exists as it marks the border for the midnight sun and the winter darkness.

 

The midnight sun - or rather the 24 hours sun is due to the earths inclination just as the seasons are. The sun that shines within the polar circle parts of the year, shines 24 hours a day and rotates in the sky. At night the sun shines over the earths axel rotating point, the north and the south pole. In that way, the northern areas have bright nights and the midnight sun. In winter, the sun does not reach over the

The Polar circle is the border around the poles where the sun shines in summer over the polar axel, while the sun in winter does not reach over the polar circle, not even in the middle of the day. This is because of the earths inclination is in the shadow side compared to the sun. On the drawings above you can see how. By the polar circle, there is a difference if you stand on a mountain or stand down in a valley when the sun shines on the horizontal line.

     

Everybody knows that the earth rotates around its own axel, the north and the south pole, but it seems like that the midnight sun rotates around the horizont.  This is a phenomen that facinates many people, and they come to the northern Scandinavia,  from fare away to admire this, and many times only to experience a rainy day. The best place to view the midnight sun in in Greenland, because the weather is more stable.

The time the midnight sun lasts, depends on how fare north you are from the polar circle. The closer you come the pole (north or south), the more even the suns course is over the horizont and the longer the midnight sun lasts in summer. The same rule is for winter part of the year. On the pole there is no difference between night and day, because the sun shines the whole day in summer or is gone the hole day in winter. In between summer and winter, there are weeks of twilight.

On the north and the south pole, it is there for not the earths rotation around its pole that makes day and night once a day, but the rotation around the sun it self. Strange enough the moon circles act the same way. Either it is completely gone, or it is rotating in the horizont.
