Mercury, Venus and Saturn appearing above the pyramids of Giza creates a striking meeting of ancient architecture and the Solar System. All the planets orbit the Sun close to roughly the same plane, called the ecliptic. From Earth, this means planets regularly appear along the same narrow path across our sky and can occasionally form impressive-looking alignments. The pyramids themselves were built more than 4,500 years ago, with the Great Pyramid of Giza completed around 2560 BCE. Since then, countless planetary configurations have appeared above them. Claims that this particular Mercury-Venus-Saturn arrangement occurs only once every 2,373 years should be treated cautiously. Planetary alignments depend heavily on how precisely “alignment” is defined, the observer’s location and the required angular separation. There is also no astronomical evidence that the three planets intentionally align with the three pyramids. Their apparent positions relative to the monuments change simply by moving the camera. Still, the scene represents an extraordinary contrast in scale: structures thousands of years old beneath planets located tens of millions to more than a billion kilometers away.
