WebA 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 … Examples: Antares (Alpha Scorpii) is a red supergiant star in a binary system with a hotter blue main-sequence star Antares B.
