Alnitak (Zeta Orionis) is one of the three stars that make up the "Belt of Orion." In the Northern hemisphere, it is usually seen as the bottom star.
Alnitak actually is a triple star system: one blue supergiant (Alnitak Aa), which has two bluish companions (Alnitak Ab and Alnitak B). Alnitak Aa and Ab form a close binary, which together are a distant binary to Alnitak B. Alnitak B orbits Alnitak A every 1500 years. The existence of a fourth star, Alnitak C, is suspected but has thus far not been confirmed.
Alnitak lies at a distance of approximately 736 light years.
Orion's Belt: Alnitak - Alnilam - Mintaka
Robert Bauval was the first to point out that the Great Pyramid in Gizeh appears to be a representation of Alnitak. Since then a number of authors, including South African author Wayne Herschell have discovered that a number of ancient monuments are set up in a way that mimics Orion's Belt.
Two contact cases refer to one or two planets that could be located in the vicinity of Alnitak:
- Nep-4, mentioned in the contact case of Oswald Gonzalez
- Zeti, mentioned in the contact case of Raphael Chacun
