📸 Two Worlds, Two Analemmas
An analemma shows the Sun’s position at the same time each day over a year. Earth’s forms a figure-8. Mars, with a more eccentric orbit, creates a teardrop shape. The images were taken from Earth (2011–2012) and by the Opportunity rover on Mars (2006–2008).

A split image showing two analemmas: one on the left taken from Earth, and one on the right taken from Mars by the Opportunity rover. The Earth analemma appears as a symmetric figure-8 shape in the sky, while the Martian analemma appears teardrop-shaped due to Mars’ more eccentric orbit. Both are created by stacking multiple images of the Sun taken at the same time of day over the course of a year. The ground below shows a fixed foreground landscape for reference.
