Observers can never see all 88 constellations from a single location on Earth. While some of the southern constellations can be seen from northern latitudes at certain times of year – Scorpius, for instance, is visible over the southern horizon in the summer – others never rise over the horizon. Crux, also known as the Southern Cross, which is prominent enough in the southern sky to be featured on several national flags in the southern hemisphere, can never be seen from most locations north of the equator. Similarly, the constellation Ursa Minor, which contains Polaris, the closest bright star to the north celestial pole, cannot be seen from most places south of the equator.
Why do we see different constellations at different times of the year?
As the Earth orbits around the Sun, constellations move slowly to the west over the course of a year and we see different parts of the sky at night because, as the seasons change, we are looking in a different direction in space. This means that different constellations are viewable at different times of year.

Do stars move farther from the celestial poles?
Polaris and other stars lying near the celestial poles appear to move across a smaller area than stars lying closer to the equator. The farther they are from the poles, the wider the circle the stars make across the night sky. The stars that are close to the poles never set below the horizon for observers in locations where the stars are visible: they are circumpolar. Near the equator, there are no circumpolar stars. With the celestial poles on the horizon, all stars appear to rise in the east and set in the west for observers at the equator.
