Orion's Belt or The Belt of Orion is an astronomical asterism in the constellation Orion. It consists of the three bright stars ζ Ori (Alnitak), ε Ori (Alnilam), and δ Ori (Mintaka). Alnitak is approximately 800 light years away from Earth and considering ultraviolet radiation, which human eye can not see, Alnitak is 100,000 more luminous than Sun. Alnilam is approximately 1340 light years away from Earth and shines with magnitude 1.70. Considering ultraviolet light Alnilam is 375,000 times more luminous than Sun. Mintaka is 915 light years away and shines with magnitude 2.21. Mintaka is 90,000 times more luminous than Sun. Mintaka is a double star. Both stars orbit around each other every 5.73 days. Looking for Orion's Belt in the night sky is the easiest way to locate constellation Orion in the sky. In the Northern hemisphere, Orion's Belt is best visible in the night sky during the month of January at around 9.00 PM when it is approximately around local meridian.
