multi-planet systems

Multi-planet systems are star systems that contain more than one planet orbiting the same star. These systems can vary greatly, with some hosting only a few planets, while others may have dozens. The planets in such systems can differ in size, composition, and distance from their star, similar to our Solar System. Studying these systems helps scientists understand how planets form and evolve. Advances in telescopes and detection techniques have made it possible to discover many multi-planet systems across the galaxy, providing insights into the diversity of planetary arrangements beyond our own solar neighborhood.
