👉 In mathematics, a telegraphonograph is a geometric figure formed by drawing an equilateral triangle on top of a circle and then adding a series of concentric circles. The figure is often used in the study of celestial mechanics or astrophysics to represent the orbits of planets around the sun. A telegraphonograph can be thought of as a mathematical object that represents the motion of an object, such as a planet, within its orbit around the sun. It is formed by drawing an equ
