Binary star definition astronomy
A binary star is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved using a telescope as separate stars, in which case they are called visual binaries. Many visual binaries have long orbital periods of several centuries or millennia and therefore have orbits which are uncertain or poorly known. They may also be detected by indirect techniques, such as spect… WebIn astronomy, a binary system is one that consists of two stars that are gravitationally bound. The two stars obey Kepler’s laws of motion, and orbit their common centre of mass in elliptical or circular orbits. Some …
