In which direction does the sun rise
Courses & tours
In the east the sun rises, in the south it rises high, in the west it will set, in the north it can never be seen. This motto is meant figuratively, because as a fixed star the sun does not move, but the earth rotates once around its own axis in the course of a day (24 hours).
The position of the sun is the position of the sun in the sky above an observation location, indicated by the horizontal coordinates of height and direction (azimuth). It changes over the day as a result of the earth's rotation and over the year as a result of the earth's orbit around the sun.
Would you like to know the position of the sun at a certain point on earth and, for example, visualize the shadow of a tower?

Did you know that the moon moves further and further away from the earth, by around four centimeters every year? The average distance is about 382,900 km.
The distance between the earth and the moon changes constantly - depending on which part of the orbit the earth is currently in. This is because the moon's orbit around the earth is elliptical. If the distance from the moon to the earth is greatest, it appears to us about 12-14% smaller.
If the moon comes particularly close to the earth, it appears in the night sky about 7% larger than an average moon. If this point in time coincides with the full moon or new moon, one speaks colloquially of the “super moon”. Although the lunar surface itself is not brighter, about 30% more moonlight reaches us during a super moon.
