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.

What Constellations are visible all year?
The constellations near the plane of the ecliptic (the zodiacal constellations) are only visible at certain times of the year. The constellations towards the poles (N and S) are visible at all times of the year from their respective hemispheres. In the South, the Southern Cross would be one example and in the North the Great Bear (or plough) would be another.
Why do some constellations such as ursa minor are visble in the sky year round other constellations appear for only part of the year?
What constellations are circumpolar (visible all year, at any time of the night) depends on your latitude. If you are (for example) at a latitude of 50° north, then any start that is 50° or less from the sky's north pole will never go below the horizon. For a more detailed explanation, read the Wikipedia article on "Circumpolar star".
What three constellations are made of only four stars?
Corvus,Cancer,and Libra.
How many constellations are there within the path of the sun in the sky throughout the year which also known as the zodiac?

Who is the astronaut of Jupiter?
Nobody. The only celestial object ever visited by astronauts is the moon.
Why can't you see all the constellations at once?
The Earth is a sphere. An observer looking up can only see the stars on their side of the planet. As the Earth rotates, it exposes the observer to the other stars visible to their hemisphere. Simply put, the earth gets in the way. If the earth were to disappear and you were floating in space, you could freely look around at the celestial sphere and observe the constellations. The number of constellations visible would be limited only by the range of your vision, which still would be insufficient to see in every direction simultaneously.
How is a planetarium similar to a celestial sphere?
The inside of a planetarium is a sphere with the stars and planets projected on to it. The celestial sphere is an infinite sphere that we imagine has the stars and planets on it. On the celestial sphere only an object's direction matters and its distance is ignored. A viewer at the centre of the planetarium sees stars and planets as they appear in the sky, but viewers in all the seats see approximately the right view.
How do you use the archaic model of the celestial sphere today?
Archaic models are studied only to understand the evolution of human thought.
What are the only constellations visible all year long?
The region of the sky visible all year round is called "circumpolar". What stars and constellations are included there depends on your geographical location. For example, for somebody living 30 degrees south of the equator, a region around the south pole of the sky, with a radius of 30 degrees, would be circumpolar.
Where was the titan atlas from?
Atlas was born in Greece. He was NOT a god, he was a titan. He sided with the Titans in the war of the Titans and Gods. He was only there to hold up the heavens and the celestial sphere.
Where would you go on earth if you wanted to be able to see both the north celestial pole and the south celestial pole at the same time?
To see both the north celestial pole and the south celestial pole at the same time a person would need to standing at the equator. The atmospheric haze may interfere near the horizon may obstruct the view.
Is Venus the only planet that rotates clock wise?
