What did Apollo do to Orion?

In Greek mythology, Apollo killed Orion, a giant huntsman, out of jealousy or rivalry. The reasons vary by myth; in one version, Apollo was threatened by Orion’s growing fame and prowess, while in another, he was angered when Orion attempted to pursue his sister, Artemis. To rid the world of Orion, Apollo tricked him into swimming out to sea and then shot him with a deadly arrow. After his death, Orion was placed among the stars as a constellation.
