It is formed by the three bright stars Alnitak, Alnilam and Mintaka.

Beautiful and seeable from almost every part of our planet, they are some of the most brightest stars in the sky.

Very fascinating phenomenon, the Orion’s belt it is composed by Alnitak and Alnilam, two blue supergiants stars, the most brightest stars of all, and by a very interesting star called Mintaka, that is a very rare multiple star system formed by six different stars.

Ever since very past times, every culture saw them, so there are a lot of legends regarding them; for example, for Christians they represent the three magi while for Arabians they represent three pearls.
