The western most star in the Orion constellation ‘belt’ – known as Mintaka (‘the belt’ in Arabic) also called Delta Orionis by astronomers – is a triple star system + 2 other stars. Strong x-ray emission have been detected by NASA’s Chandra X-ray Telescope emitted by a eclipsing binary star and a third star in orbit around them.
