Solitary stars like our Sun are actually a cosmic minority. More than half of all stellar systems feature two or more stars bound by gravitational pull.

Image credit: NASA ScienceEclipsing binary systems periodically block light from Earth's viewpoint. Tracking these minute dimming events enables astronomers to calculate stellar masses, diameters, and orbital paths accurately.
Image credit: NASA ScienceComplex gravitational dances exist in systems like TYC 7037-89-1. Six stars organize into three distinct binary pairs that orbit each other in a tightly synchronized dynamic.
Image credit: NASA ScienceCollapsed remnants like white dwarfs or neutron stars siphon material from close companions. Superheated gas falling onto these dense bodies generates intense X-ray radiation.
Image credit: NASA ScienceDense neutron stars in binary arrangements gradually spiral inward and collide. These catastrophic impacts forged many of the heavy elements scattered across the universe today.
Image credit: NASA SciencePlanets can orbit within multi-star systems, experiencing complex skies. Even Proxima Centauri, part of a triple-star system, hosts at least one confirmed alien world.
Image credit: NASA ScienceStudying complex multi-star dynamics helps scientists map gravitational interactions and galactic history. Open questions remain about how such intricate stellar architectures form and endure.
