Mintaka

Mintaka is one of the three stars of the belt of the Orion constellation. The name means "Belt" in Arabic.

Mintaka is actually a binary star, consisting of a class B giant and a smaller but hotter class O. The stars orbit each other every 5.73 days.

In 1904, Johannes Hartmann discovered that interstellar space contains a thin gas, by using Mintaka as a background source (see interstellar medium).
