APOD #7

This photo shows the progression of the Sun's movement in our sky over a year. A picture was taken every day while the sun was out, highlighting the figure-8 movement called the analemma. The last day in the photoset included a total eclipse of the sun on the Winter Solstice analemma, called a Tutulemma. Each analemma looks different depending to the latitude at which the photo is being taken. Venus is also visible in the bottom right region of the photo.

This figure-8 movement gives us clues about how the earth moves incomparison with the Earth's movement. While the Earth moves in an ellipse about the sun, the sun appears to create an analemma to viewers on Earth.
