Astronomical gears, also known as planetary gears, are a type of gearing system that consists of a central gear, called the "sun gear," and multiple smaller gears, referred to as "planet gears." These gears revolve around the sun gear while simultaneously meshing with it, resulting in a highly efficient and powerful transmission. Planetary gears can be found in various applications, including automotive transmissions, industrial machinery, and even small consumer products like toys and tools.
