 The same source tells two stories of the death of Orion . The first says that because of his " living joined in too great a friendship " with Oenopion , he boasted to Artemis and Leto that he could kill anything which came from Earth . Earth objected and created the Scorpion . In the second story , Apollo objected to his sister Artemis 's love for Orion , and , seeing Orion swimming with just his head visible , challenged her to shoot at that mark , which she hit , killing him . He connects Orion with several constellations , not just Scorpio . Orion chased Pleione , the mother of the Pleiades , for seven years , until Zeus intervened and raised all of them to the stars . In Works and Days , Orion chases the Pleiades themselves . Canis Minor and Canis Major are his dogs , the one in front is called Procyon . They chase Lepus , the hare , although Hyginus says some critics thought this too base a prey for the noble Orion and have him pursuing Taurus , the bull , instead . A Renaissance mythographer adds other names for Orion 's dogs : <unk> , <unk> , <unk> , <unk> , <unk> , <unk> , <unk> , <unk> .
