The answer depends on how long the night is. With respect to distant stars the earth rotates once in every 23 hours 56 minutes and 4 seconds. Over that period, the stars will move through 360 degrees.

How many degrees do the stars move around polaris in 3 hours?
45 degrees
Stars move around polaris at what degree?
15 degrees per hour.
How do the stars appear to move near Polaris?
Polaris traces out a circle with a diameter of 1.5 degrees above the North Pole. Other nearby stars trace out larger circles.
Why doesn't Polaris seem to move?
The apparent "movement" of the stars through the night sky is due to the rotation of the Earth. The observer on Earth is going around in a big circle every day. The center of that circle is the axis of rotation of the Earth. (The longer term movement due to the orbit around the Sun every year does not affect the apparent position of the stars because they are so far away.) Polaris is (almost) in line with the Earth's axis of rotation. At night, as the Earth rotates, Polaris appears to stay at one point in the sky as the sky rotates around it. That point is the North Celestial Pole. Polaris is used for simple navigation because it is at a height in degrees above the horizon equal to your North latitude. (At the North Pole it would be straight up, so 90 degrees. In London, for instance, that number is 51½ degrees.)
What appears to revolve around Polaris due to earth's rotation?
Due to the vast distance between the earth and polaris, the earths axis of rotation essentially lines up with polaris at all times, so when the stars are visible, and viewed from the north pole, the earths rotation causes the stars to appear to rotate around polaris.
What causes the circumpolar stars to appear to move around polaris?
The apparent daily movement of the stars in the sky is a reflection of Earth's rotation. Earth rotates around its axis; as a reflection of this, the entire sky rotates around an "axis", which is simply the extension of Earth's axis. By chance, the star Polaris is almost exactly on the line of the Earth's axis, extended into space. So, as the Earth rotates the stars appear to rotate around Polaris. Circumpolar stars never go below the observer's horizon, so they just seem to go in circles around Polaris.
Which of these stars is closest to the earth Polaris Antares or Betelgeuse?
Polaris is the closest of the three stars.
Circumpolar constellations orbit what?
Beautiful question !! Circumpolar stars and constellations are stars and constellations the "go around the pole" = Circum (circle) polar (the pole) The North Star is called "Polaris" because it's directly above Earth's North Pole - in other words, if you went to the North Pole, "polaris" would be directly over your head. Because of this, all of the stars appear to pivot around Polaris as Earth rotates. Now I don't know where you live, but if you live in the United States, Polaris would NOT be overhead - it would be lower in the sky but still in the North. The lower on the globe you live, the lower Polaris appears in the sky. So, the stars and constellations that spin around Polaris but DON'T SET, are called circumpolar stars and constellations.
Why do the stars appear to rotate around Polaris?
It's an illusion caused by the actual rotation of the earth.
What is the altitude of Polaris if your latitude is 41 degrees south?
You would never see Polaris there because it would always be 41 degrees or more below the northern horizon. On the other hand you can see many fine stars and constellations that are never seen in North Europe or the north of the USA and Canada.
Is Polaris moving?
Yes, Polaris is moving, as are all stars in the galaxy.
Which star is in the north star?
The North star is called Polaris. Polaris is the brightest star in the constellation Ursa Minor. It is not the brightest star in the night sky; that title goes to Sirius, in Canis Major. Polaris has 2 companion stars: Polaris AB and Polaris B. It's spectral type is F7 Ib-II SB.
