Mintaka

Orion constellation map showing Mintaka as Delta (δ) 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]

Alnitak, Alnilam, and Mintaka, are the bright bluish stars from east to west (left to right) along the diagonal in this gorgeous cosmic vista. Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie about 1,500 light-years away.Astronomy Picture of the Day on 10 February 2009
