The westernmost of the stars that make up Orion's Belt is also the faintest, as seen from Earth. In fact, Mintaka is a highly luminous body, but appears faint due to its great distance: it is almost seven hundred light years from the Solar System. At a distance of ten parsecs, it would shine more brightly than the planet Venus.
