Why would constellations near polaris be seen all year round by people in the northern hemisphere?

Also known as the North Star, Polaris, is located within one degree of the north celestial pole - the point of Earth's axis of rotation. This means that the Earth's (geographic) north pole is pointing almost exactly to the point in the sky where Polaris is located. For this reason, Polaris can be seen by anyone in the northern hemisphere throughout the year.

Why can we only see the constellations in the north of the celestial sphere?
This is true if you live in the northern hemisphere. You can't see the southern stars because the bulk of the Earth is in the way. Different constellations are visible in each hemisphere, a constellation in the northern sky can be difficult or impossible to see from the southern hemisphere of the Earth, and vice versa. The reason is that the axis of the Earth's rotation is fairly constant. In its annual journey around the Sun it generally points in the same direction; people in the northern hemisphere will generally see the same constellations year round, and the same in the southern hemisphere. Those living near the equator see some of both. The tilt of the Earth's axis also makes some constellations somewhat seasonal, because of a slight change of the viewer's angle to the night sky.
Who introdous the oldest descriptionof the constellation?
The first constellations were, we believe, invented by the ancient Babylonians and Sumerians, and perhaps the Phoenicians. These were to give people a way to refer to the stars and constellations, and provided a heavenly anchor for their stories. Most of the northern hemisphere constellation names that we use today were invented, or adapted, by the ancient Greeks and Romans. The southern hemisphere constellations were largely named by sailors and mariners. It's likely that the people who lived in these southern lands had names of their own for the constellations and stars, but few of those are still in use.

How do fishermen use constellations?
The constellation Ursa Minor, the little bear, contains the star Polaris which, in modern times appears to remain stationary above the North Pole. This can help people in the Northern hemisphere locate the northward direction.There are other constellations which rise and set at different times of the night in different seasons. This information can be ueful in telling the time.

What star helps people navigate in the northern hemisphere?
Polaris, the 'North Star', which never sets, and indicates the direction of north. Polaris is the last star in the handle of the Little Dipper, Ursa Minor. ('Little Bear,')
Can same star constellations be seen from Europe and Australia?
Some of them, yes. Constellations along the Zodiac can be seen from either hemisphere, but constellations well away from the celesial equator cannot be seen very far in the other hemisphere. For example, Ursa Major is not visible in Australia, and the Southern Cross is not visible in Europe or North America. Most of the "official" constellations were named by northern hemisphere astronomers, or European navigators sailing in southern waters. Look at how many southern hemisphere constellations have a nautical theme; the Telescope, the Octant, the Quadrant. Even Cetus, the Whale, was named by sailors, not people who LIVED there.
Are there more people in southern hemisphere or northern hemisphere?
There are more people living in the northern hemisphere compared to the southern hemisphere. This is because the majority of the world's population is concentrated in countries located in the northern half of the globe.

Why do people who live in Australia never see Polaris?
People who live in Australia can indeed see the star Polaris. They just have to visit the northern hemisphere to do it. The earth's axis has a reasonably stable orientation toward north/south; thanks to the stabilizing effect of the moon, it doesn't swing wildly out of place. So people viewing the sky from closer to the north pole can see the northern sky and not the southern sky. People viewing the sky from closer to the south pole can see the southern sky and not the northern. Polaris is very close to the point the north pole actually points to, which is why it is called 'Polaris', the pole star.
