For a year, the Sun writes a figure eight in the sky
By Pictolic https://pictolic.com/article/for-a-year-the-sun-writes-a-figure-eight-in-the-sky.htmlDo you know that relative to an observer on Earth, the Sun spins a figure eight across the sky?
We are talking about analemma. This is a line connecting the points of the position of the Sun in the sky at the same time of day during the year - if observed from the same geological location. The tilt of the earth's axis creates the appearance that the sun changes its position in the sky every day.
You can do the analemma yourself. All you need is a tripod, a camera and a little patience. Just set the camera in a certain position and take several pictures every day at the same time.
