Here's why:

* Orion is a winter constellation in the Northern Hemisphere. This means it's visible in the evening sky during the winter months.

* Fall: Orion starts to become visible in the early evening hours as the nights get longer.

* Winter: Orion is at its highest point in the sky during the winter evenings, making it most prominent and easy to spot.

* Spring: Orion begins to set earlier in the evening as spring approaches. By late spring, it's no longer visible after sunset.

Best viewing times in North America:

* October - April: You can see Orion throughout this period, with visibility improving as winter progresses.

* December - February: This is the prime time to view Orion as it is high in the sky for the longest period.

Remember to find a location with minimal light pollution for the best viewing experience!
