What makes Orion move?

At night we look up at the vastness of star studded space. The view changes as the earth spins on its axis. The stars seem to whirl around us, parading from east to west over the sky. Tilted on its axis, the earth orbits the sun. Throughout the year we get a changing view of star spattered outer space, We see dazzling Orion in the winter and the snaky Scorpion in the summer. The faraway stars are fixed in their places and these changes are not what they seem to be,

In early fall, Orion rises in the east soon after sunset, Each week when darkness falls, the dazzling constellation is higher in the sky. In early spring it sets soon after the sun.
