Regular moons are natural satellites that orbit their planets in a consistent and predictable manner. They typically have stable, circular or elliptical orbits and maintain a synchronous rotation, meaning they rotate on their axis at the same rate that they orbit their planet. This results in the same side of the moon always facing the planet. Most of the major planets in our solar system, such as Earth with its moon, Mars with its two small moons, and Jupiter with its many moons, have regular moons. These moons can vary in size, composition, and geological activity, contributing to the diversity of celestial bodies in our solar system.
