Sun’s Annual Journey Across The Sky Creates Figure Eight (13 Pics)
Did you know that from Earth’s perspective the sun is constantly moving in a figure-of-eight pattern?
It’s called an analemma – a diagram that depicts the sun’s movement in the sky over a period of one year, when observed from a fixed position on the Earth. This happens because of the Earth’s axial tilt making it look like our sun is changing its position in the sky every day.
You can easily do your own analemma. What you’ll need is a tripod, a camera and quite a bit of patience. Just keep the camera at a fixed location and orientation and take multiple shots throughout the year, always at the same time of the day.
Oh, and make sure to scroll down to the bottom of the gallery where you’ll find Lunar analemma and even one from Mars!
