visual binaries
Visual binaries are pairs of stars that are close enough to each other in the sky that they appear as two distinct points of light. We can see these stars individually through telescopes, and they are in orbit around a common center of mass, meaning they influence each other's movements due to gravity. Over time, astronomers can study their orbits to learn about their masses, distances, and other properties. This information helps us understand more about the characteristics of stars and the evolution of star systems in the universe.

Visual binaries are pairs of stars that appear close to each other from our viewpoint on Earth. They are called "visual" because they can be directly observed with a telescope. These stars are typically gravitationally bound, meaning they orbit around a common center of mass. Studying visual binaries helps astronomers determine important properties like their masses and distances, which can reveal insights about stellar formation and evolution. Unlike some binary systems that are detected through indirect methods, visual binaries allow for direct observation, making them a valuable tool in the study of the universe.
