No, Orion is not seen only in the winter. While it is most prominent in the Northern Hemisphere's winter sky, it is actually visible for a good portion of the year.

Here's why:

* Earth's Tilt: The Earth's tilt causes different constellations to be visible at different times of the year. During winter, the Northern Hemisphere is tilted towards Orion, making it more prominent.

* Seasonal Shift: As the Earth orbits the sun, the constellations we see shift throughout the year. Orion is visible in the evenings from late summer to early spring.

* Location: Your location on Earth also affects which constellations you see. Orion is visible from most of the Northern Hemisphere, but the timing of its appearance may vary.

So, while Orion is a winter constellation in the Northern Hemisphere, it's not exclusively a winter sight. You can catch it in the evening sky for a significant part of the year.
