the solar anus

The “solar anus” is a term used in astronomy to describe a unique feature on the planet Mercury. It refers to a highly distinctive, bowl-shaped depression near Mercury’s south pole that resembles an anus when viewed from above. This feature is part of Mercury’s geological structure, formed by volcanic and tectonic activity over millions of years. The term is metaphorical, highlighting the shape’s appearance rather than implying any biological function; it helps scientists describe and identify this unusual, rounded depression on Mercury’s surface.
