Circumpolar constellations appear to rotate around?
polaris...
Do the stars in the constellation Ursa major appear to rotate clockwise or counterclockwise?
In the Northern Hemisphere, when facing North, towards the Pole Star (Polaris) Ursa Major and surrounding constellations, rotate counter-clockwise (right to left).Turn round to face south (with Polaris behind you) the stars rotate clockwise (left to right).
Why do the stars appear to rotate around Polaris?
It's an illusion caused by the actual rotation of the earth.
How does the big dipper appear to be moving in relation to the star polaris?
The Dipper appears to rotate in a East to West direction around the celestial North Pole - which is a point that is very close to Polaris.
Does constellation Orion rotate about the pole star?
All the constellations appear to rotate round the pole star because the pole star is in line with the axis that the Earth rotates around with us on board.
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 way does the Big Dipper rotate around Polaris?
Clpckwise
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.
Who discovered that the constellations rotate?
constellation does not rotate at all, but the Earth does
Why could sailors not use constellation in navigation.?
Most constellations are circumpolar. Over the course of a night they appear to rotate around the North pole and so do not identify a specific direction. As a reult they are of little use for navigation.
Why does the starry sky over the north pole appear to rotate counter clockwise around one star polaris?
That happens because that star Polaris just happens to be in line with the polar axis of the Earth, in other words a line from the south pole to the north pole would eventually pass through Polaris. Actually it is not exact but Polaris is within one degree of the true pole.So if you sit out and watch Polaris its direction will never change as the Earth rotates with you sitting on it. It's always in the same place (almost) and if you try an experiment with a globe you can see why.On the other hand all the other stars appear to rotate.
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.
