No. As the hours go by ORION, like any "equatorial" constellation (explained below), will move across the sky from east to west. This is due to the Earth's daily rotation on its axis.

Our Sun is on the Orion spiral arm, about two-third from the center. It is difficult to detect the spiral arms in our galaxy because 1) we are inside the galaxy and 2) the gas and dust, which form dust lanes, block our view.
Examples include Procyon (F5 IV), the supergiant Canopus (F0 Ib) and the main sequence star π3 Orionis.
