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.
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.
The stars all rotate about an imaginary axis line that goes through the poles of the earth. From our veiw point, the fixed stars will move across the sky, corresponding to this spin. The polaris star is almost on this imaginary axis line - if you were to carry on extending it out to this star.
All stars appear to move due to Earth's rotation, but the Pole Star, also known as Polaris, remains in a relatively fixed position in the sky because it is located almost directly above Earth's North Pole. This causes it to appear stationary as other stars appear to rotate around it.
counterbalancer is bad
Bad float valve in carb
Uhh... being in a well lit area..?
The rotation of the earth is what causes the sun to appear to set
It's broke
Fluorescein stain causes the cornea to appear green with lit with a Woods lamp.
Yes, Polaris will no longer be the North Star in around 12,000 years due to the Earth's axial precession, which causes the position of the North Star to change gradually over time. The next star to take its place as the North Star will be Gamma Cephei.
The north star doesn't appear to move because it is at the tip of the axis of the Earth so we view it as not moving. All stars move because they are full of energy and ready to zoom. The north star is also moving, but since the Earth is spinning so quickly it seems to not be moving. Hope this helps :).
Check the air filter on the 98 Polaris first for a clog. If the filter is on, check the exhaust lobe on the cam, as they are known to wear and cause this problem.
