ANALEMMA- THE INFINITY FIGURE DANCE OF SUN.
– An Analemma is the diagram showing the position of the Sun in the sky, as seen from a fixed location at the same time, throughout the year. Its structure looks similar to that of the figure: “8”.
But unlike the figure of 8, the two loops of the Analemma are unequal in size with one of them larger than the other. In astronomy, the Analemma is considered one of the most difficult and demanding phenomena to image because it is never present all at once. It requires a virtual image made at the same time of day on 30 to 50 days throughout the year.
Analemma has its significance in astronomy as the study of it gives us a better understanding of the Earth’s revolution around the Sun and about our solar system.
Two factors contribute to the formation of the Analemma pattern and they are completely independent of each other.
The two factors are as follows:
1) Earth revolves around the Sun in an elliptical orbit.
2) The Earth is tilted on its axis 23.5° about the plane of its orbit around the Sun.
Both of these factors contribute to the formation of Analemma independently. Down below is the beautiful phenomenon of the Sun and earth dancing into infinity.
