(Redirected from Delta Orionis)

Mintaka, also called Delta Orionis, is a multiple star system in the constellation Orion. It is the right star (northern hemisphere, or left star in the southern hemisphere) of the line of stars called Orion's Belt. It is over a thousand light years away from the Sun and consists mostly of bright blue stars. The largest and brightest of the stars is a blue bright giant 24 times the mass of the Sun and 17 times wider.[1] Mintaka is surrounded by many fainter stars.[2]
