How far away is Alnitak?
Alnitak is approximately 817 light years away from Earth.
How luminous is alnitak?
Alnitak is a very interesting star, because it is not one, but three stars. The main star, Alnitak Aa, with a luminosity 100000 times that of the Sun is orbited at 11 Astronomical Units (roughly the distance at which Saturn orbits the Sun) by Alnitak Ab, with a luminosity of 20000 times that of the Sun. This binary star system is orbited at 680 AUs (roughly the distance of the inner Ort Cloud from the Sun) by Alnitak B, whose luminosity is roughly 10000 times that of the Sun.
What type of star is Alnitak?
Alnitak is a very interesting star, because it is not one, but three stars. The main star, Alnitak Aa, is a type 09.5 blue supergiant that is orbited at 11 Astronomical Units (roughly the distance at which Saturn orbits the Sun) by a type O blue dwarf that astronomers call Alnitak Ab. This binary star system is orbited at 680 AUs (roughly the distance of the inner Ort Cloud from the Sun) by the bluish-white type B0 Alnitak B.

Apparent magnitude of Orion stars?
There are 81 stars in the constellation which appear in the Bayer/Flamsteed catalogues. Eight of these are brighter than an apparent magnitude of 3.0 The seven which from the notable hour-glass outline are:Betelgeuse (Alpha Orionis).Rigel (Beta Orionis)Bellatrix (Gamma Orionis),Mintaka (Delta Orionis),Alnilam (Epsilon Orionis),Alnitak (Zeta Orionis) andSaiph (Kappa Orionis).Of course, as with any constellation, there are stars which are so faint that they have not yet been detected and so have not had their magnitudes measured.
How did the star Alnitak get its name?
Alnitak's name comes from the Arabic phrase al-Nithāq, which means "the girdle" as it is part of the three stars that form Orion's Belt. It is also sometimes referred to as Zeta Orionis in the Bayer designation system.
What is the size of alnitak star?
Alnitak, also known as Zeta Orionis, is a massive blue supergiant star located in the Orion constellation. It has an estimated radius about 20 times greater than that of the Sun and is approximately 100,000 times more luminous. Alnitak is part of a triple star system, with its two companion stars being less massive but still significant in size. Its immense size and brightness make it one of the prominent stars in the night sky.
