In the northern hemisphere there are some stars that do not appear to rise or set as other stars do These stars are?
Circumpolar stars. In the northern hemisphere, the north star does not rise or set; the north pole is always pointing toward it. The canopy of stars moves around the north star over the course of a day, giving the apparent rising in the east and setting in the west of most stars as the canopy dips below and moves above the horizon. The stars that are close enough to the north star never set. The part of the canopy that is visible at night changes over the course of a year.

What is the southern hemisphere?
The southern hemisphere is the half of Earth that is south of the equator. It includes continents like Australia, Antarctica, most of South America, and parts of Africa. Seasons in the southern hemisphere are opposite to those in the northern hemisphere.
If observing the sky from the northern hemisphere which direction would the stars appear to move that are near the north celestial?
When in the northern hemisphere, looking north toward the celestial "axis" or North Star (aka Polaris), stars acan be oberserved to move all directions. To the south of Polaris (looking "above" it), the stars and other things move East to West across the sky. To the north of Polaris (looking "below" it), the stars and other things move West to East across the sky. Both are true for short distances, because in fact, the direction it moves is actually in a smaller and smaller circle the closer the star appears to be to Polaris. With a camera that can take long exposures (10-20 minutes or even hours) this circular motion can easily be seen.
Star Movement across sky southern hemisphere?
In the southern hemisphere, stars appear to move from east to west in a clockwise direction due to the Earth's rotation. Polaris, the North Star, is not visible in the southern hemisphere. The Southern Cross and the constellation Crux are prominent in the southern sky and can be used for navigation.
From a northern hemisphere perspective all stars appear to change positions except one which appears fixed. What is the name of that star?
The star that appears fixed from a northern hemisphere perspective is called Polaris, also known as the North Star. It is located almost directly above the North Pole, making it a useful navigational tool for determining direction.
Is Sirius visible at night in the northern hemisphere during the summer?
Yes, Sirius is a bright star and is visible in the northern hemisphere during the summer months. It is one of the brightest stars in the night sky and can be seen low on the horizon in the southeast during the summer evenings.
From the northern hemisphere circumpolar stars appear to be circling what?
From the northern hemisphere, circumpolar stars appear to be circling around the North Star, also known as Polaris. This is because the North Star is located near the North Celestial Pole, making it a fixed point in the sky around which the circumpolar stars appear to revolve.
In which direction do the stars appear to move?
The stars appear to move from east to west across the night sky due to Earth's rotation on its axis. This motion creates the illusion that the stars are moving, when in fact it is our own planet that is rotating.
How can you tell what the directions are from the stars in your hemisphere?
In the northern hemisphere you want to look for Polaris or the northern star. This star is special as it does not move much, and is always in the north. All of the other stars appear to rotate around it as the earth spins on it's axis. You can find this star by looking for the Big Dipper, take the end two stars opposite the handle and continue the imaginary line further until you get to it, the end of the Little Dipper. In the Southern Hemisphere, look for the Southern Cross.
What was the north Star to?
Polaris, the North Star, has been used for navigation in the northern hemisphere for centuries. It is reasonably static, while the Earth's rotation makes all the other stars appear to circle round it.
How many stars can be seen from the northern hemisphere?
infinite
Are there more stars in the southern hemisphere?
Yes, there are more visible stars in the southern hemisphere than in the northern hemisphere because the southern hemisphere has fewer large cities and less light pollution, which allows for better visibility of stars. Additionally, the southern hemisphere has the center of the Milky Way galaxy, which contains more stars than the outer regions where the northern hemisphere is situated.
What star does the other northern hemisphere stars seem to rotate?
The stars in the northern hemisphere appear to rotate around the North Star, also known as Polaris. This is because Polaris is located very close to the Earth's north celestial pole, making it a useful reference point for navigation.
Can you see northern hemisphere stars from southern hemisphere?
Some northern hemisphere stars can be seen from the southern hemisphere depending on the latitude. For example, Polaris, the North Star, cannot be seen from the southern hemisphere. However, stars like Vega and Capella can be visible from both hemispheres.
Are the stars brighter in the southern hemisphere than the northern hemisphere?
For the most part there is less developed land in the Southern Hemisphere than in the Northern Hemisphere. That means that at night when you can see the stars there is less light pollution, and generally, I believe. less air pollution. Less air pollution means less tiny particles in the air. Particles tend to interfere with the passage of light, so you can't see stars that give off less light. At the same time "Light Pollution" makes the sky seem lighter providing poorer contrast and making weaker stars more difficult to see. In other words, stars are not brighter in the Southern Hemisphere, they're just easier to see.
What exactly is the north star?
It is a star called Polaris. It is not a particularly bright star. It is important though. As seen from the Northern Hemisphere, it is normally seen to be in the same location and all other stars appear to rotate around that point.
What imaginary point around which southern hemisphere stars rotate is south pole?
In the northern hemisphere, we have a moderately bright star called 'Polaris' or the 'North Star' ... that happens to be located near the north pole of the sky, and the stars appear to revolve around it once a day. The stars appear to do the same in the southern hemisphere. But it's a little less obvious, because there's no particularly bright star near the south pole of the sky.
How did they find stars useful in the past?
They used them to navigate (for instance, the Southern Cross in the Southern Hemisphere or the Northern Star in the Northern Hemisphere) or to build their farming and religious calendars.
