why can we see Orion only in winter?

We can see the constellation Orion more prominently in the winter sky in the Northern Hemisphere because of the Earth’s rotation around the sun and its position in relation to the stars. The visibility of constellations varies throughout the year due to Earth’s axial tilt (about 23.5 degrees) and its orbit around the sun.

Orion appears in the sky during the winter months for observers in the Northern Hemisphere because it is situated on the celestial equator, which means it rises above the horizon and reaches a good altitude for viewing when the Earth is on the opposite side of the sun from Orion. In the winter, especially during the months of December and January, Orion is visible in the southern sky during the evening hours for viewers in the Northern Hemisphere.

Conversely, during the summer months in the Northern Hemisphere, Orion is on the opposite side of the Earth from the sun and thus below the horizon, so it cannot be seen at night.

It’s important to note that for observers in the Southern Hemisphere, Orion’s visibility is reversed: it’s a prominent feature in their summer sky.
