What constellations can you see in the four seasons in the northern hemisphere?

In the northern hemisphere, Cassiopeia and Ursa major can be seen all year round.

Ursa major is one of the brightest and most important constellations in the northern sky. The famous Big Dipper is in this constellation, and the best time to observe it is after dusk in spring.

Cassiopeia is an easily recognizable constellation. Its five brightest stars form a very unique W-shape. Stay away from Ursa major, because it is close to the north celestial pole and can be seen all year round, especially in autumn night.
