The NorthStar(Polaris) isthe star that never moves in the sky asEarth rotates.
Actually, it does move a little bit, because it's notexactly over the North pole.

∙ 14y agoPolaris (the 'North Star', the 'Pole Star') is close to the point in the sky that the earth's North Pole points to.
The star is so nearly motionless that it makes a fine reference point for navigation.

∙ 14y agoThe Earth rotates on a slowly-changing axis. Any star that appears very near this axis will seem to remain in place while the Earth turns.
As the axis itself changes, so will the North Star. Today it's Polaris, but 12,000 years from now will be Vega.

∙ 14y agoDue to the mostly uniform rotation of the earth, the stars in the night sky appear to orbit the celestial pole. Polaris, the North Star, is between 1 and 2 degrees off the celestial pole, so it too moves as the night progresses, but the movement is so slight that it is imperceptible to the human eye. Consequently, Polaris has not always been the North Pole Star. Due to a phenomenon called axial precession, the North Pole Star changes, though this change takes thousands of years to complete, and Polaris will be our North Star for the foreseeable future.

∙ 10y agoThe Earth rotates on its axis.
The line of the axis points almost exactly to the North Star, Polaris.
So, as the Earth rotates, Polaris doesn't seem to move like the other stars.

What is the name for current north star?
The North Star is called Polaris. At night, it is often the brightest star in the north. It used to be used as a way to navigate at night, and still is in some parts of the world.
Why is the north star is the only star in the night sky that seems to stay still?
Because it's in line with the Earth's north and south poles, so as we sit watching from our rotating Earth its direction does not alter. Imagine sitting on a swing as it goes round. If you look at the centre, its direction stays fixed, as the rest of your surroundings appear to rotate.
When is the next shooting star in 2012?
Shooting stars appear every night.
How do you Navigate using the stars?
Look for the star that doesn't appear to move in the sky, and looks like all the other stars are rotating around it. This is the north star. Following the North star leads you north.
How do you determine true north without a compass at night?
Look for the North Star or Polaris. It sits right over the North Pole of the Earth. It is the last star in the Little Dipper.
If you look north at night and see a star left of polaris what direction will the star appear to move due to the motion of earth?
North

Which star appears to stay still in the sky all night?
This is Polaris, often also called the north star or the pole star.
Which star is visible at night?
the north star
Star which do not change its position in the night sky?
The only star that does not appear to move in the Sky is Polaris, the North Star. (Actually it does move in a TINY circle, but the apparent motion is too small to notice.)
Towards which star does the earth's axis appear to be tilted?
The north star

Which star never changes location in night sky?
All the stars appear to move in the night sky, because the Earth is spinning. But for ONE star, the movement is so small that you can't see it without a camera. This star is Polaris, the north pole star. On a long time-exposure photograph, you can see Polaris making a TINY circle in the sky above the north pole.
What way does a star a appear in night sky?
A star can only appear to an observer on the dark side of the Earth, facing away from the Sun, so that the star's light can be seen.
How does the big dipper rotate around the north star?
Not just the big dipper but all of the stars appear to rotate around the North Star because Earth is rotating. The North Star does not appear to move because it is in line with Earth's axis of rotation.
From the northernhemispherecircumpolar stars appear to be circling the?
North Star, Polaris
Where can you see the north star?
You can see the north star from anywhere in the northern hemisphere that is not cloudy and that is in night. It is easier to see the further north you are.
