👉 In physics, a coracosteon is a unit of length that measures the distance between the center of a sphere and its surface. It is defined as the radius of a sphere divided by its diameter. For example, if the diameter of a sphere is 10 meters, then the coracosteon would be 5 meters (since 10/2 = 5). This unit is often used in calculations related to spherical geometry and is commonly represented by the symbol "ρ".
