Multiple star systems are groups of two or more stars that are bound together by gravity. These systems can vary in size and complexity, with some containing just two stars, known as binary systems, while others may have three or more stars, called triple or higher-order systems. The stars in these systems can orbit each other in various ways, creating fascinating dynamics in their movements. One well-known example of a multiple star system is Alpha Centauri, which is the closest star system to Earth. It consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. These stars are located about 4.37 light-years away and provide valuable insights into the formation and evolution of stars in our universe.
