Because in mythology Orion bragged about his skills and Zeus was annoyed so he punished him by sending Scorpio to sting him but an admirer of Orion named Diana asked the gods if they could put Orion in the sky to remember him by. They agreed but as long as Scorpio was put next to him to warn against such nasty crimes. In Orion's last dying breaths he begged not to be placed near Scorpio That's why Orion is seen in the winter while Scorpio is seen in the summer.
Scorpio
Scorpio killed Orion
Probably becasue it is in another part of the sky.There is a mythological significance to this, but since it's just a made up story, it has nothing to do with the actual reason why, which is that the two constellations are very nearly opposite each other in the sky.
SCORPIO
Betelgeuse (Orion) and Antares (Scorpio).
Orion was placed in the sky in Greek mythology to honor a great hunter named Orion who was killed by a scorpion. The gods took pity on Orion and placed him in the sky as a constellation to immortalize him.
Not surprisingly - Orion!!
Orion is behind the sun in the summer sky - which is why you can't see it. Orion is visible during winter nights, in the Northern Hemisphere.
Constellation Leo is located to the east of constellation Orion in the night sky. If you are facing south and looking at Orion, Leo will be further to the left and slightly above Orion in the sky.

Orion was a giant huntsman of Greek mythology.
This is because the stars in the sky look like the outline of a Scorpion.
