👉 In mathematics, a "spherical" or "spherical" object is an object that can be considered to have all its points lying on a single sphere. This concept is commonly used in geometry and physics, particularly in the study of spherical harmonics and spherical trigonometric functions. Spherical objects are often used in astrophysics and celestial mechanics to model the orbits of planets, stars, and other objects in our solar system. They can also be used in the study of complex systems like
