The three stars in the constellation Orion's belt may look alike to you and I; however, they substantially differ under closer scrutiny.
Magnitude 1.85 Alnitak (left) and magnitude 1.65 Alnilam (center) shine with almost the same brightness even though Alnilam is almost twice as far away. Magnitude 2.4 star Mintaka (Orion's right hip) is substantially dimmer. Both Alnilam and Mintaka are bright white and Alnitak is blueish in tone.
