Analemma, why does it form the infinity sign?

If you take a picture of the Sun at the same time each day from the same location and merge them together, it forms an infinity sign. Why not an oval? No doubt there's a comprehensible way to understand this phenomenon, can someone chime in?
Why does it not form a simple oval?
My profile background is an example of this, can't seem to post a picture from my library.

No, your profile is an example of a bowling pin.

For your comparison...

Infinity=


Bowling pin=


See the difference?

Good question. I knew the basics but the devil is in the details.

It has to do with our eccentric orbit around the Sun. To sum it up, it's because our solstices occur when we are near perihelion and aphelion when a day is shortest and longest. On Mars it's a different story, a Martian analemma is more of a teardrop shape. Jupiter has a nice oval.

Your analema, btw, is fake. A complete analemma cannot be photographed perpendicular to the horizon.

Can we settle on 'digitally manipulated?"

Analemma

In astronomy, an analemma is a diagram showing the deviation of the Sun from its mean motion in the sky, as viewed from a fixed location on the Earth. Due to the Earth's axial tilt and orbital eccentricity, the Sun will not be in the same position in the sky at the same time every day.

No.

Just because something takes a shape that is visibly relevant, cerebrally does not make it absolute.

Don't listen to Phage. Your background image is completely possible in certain locations on Earth. Especially if you are standing on a sloped surface at a nearly perpendicular angle, with a slight tilt of the camera to also make the analemma perpendicular on the final image.
