What star group can be used to find the pole star?
In the northern hemisphere the direction of the north pole is indicated by the
position of the Pole star. This can be found by following the pointers in the group of stars known as the Great Bear or Plough

Polaris. It is a star, the others are constellations.
How do you test a Polaris stator?
To test a Polaris stator, first disconnect the stator from the wiring harness and use a multimeter set to the ohms setting. Measure the resistance between the stator's terminals according to the specifications in the service manual; typically, you should see a specific resistance range depending on the model. Next, check for any shorts to ground by testing each terminal to the stator housing; there should be no continuity. If the readings are outside the specified ranges or if there’s continuity to ground, the stator may be faulty and should be replaced.
What is larger in size Pollux or Polaris?
Pollux is larger than Polaris. Pollux, a binary star in the constellation Gemini, has a radius about 8.5 times that of the Sun, while Polaris, the North Star in the constellation Ursa Minor, has a radius approximately 2.5 times that of the Sun. Thus, Pollux is significantly larger in size compared to Polaris.
What is the legend behind the constellation polaris?

Is polaris on the end of the handle of big dipper or the little dipper?
Polaris is located at the end of the handle of the Little Dipper, also known as Ursa Minor. The Big Dipper is part of Ursa Major and does not point directly to Polaris.
Explain why the big dipper appears to make a complete rotation around polaris in 365 days?
The stars themselves do not move. (Well, they do, but so slowly that nobody can notice it over a lifetime.) The stars APPEAR to rise in the east and set in the west because the Earth itself is spinning like a top.
The North Pole Star, Polaris, is positioned - by a fortunate coincidence - directly over the north pole of the Earth's rotation. So Polaris does not appear to move (much). Because of the way the Earth is spinning, the stars near Polaris appear to spin around Polaris! So the big dipper and the little dipper appear to make enormous circles in the sky centered on Polaris, going around once per day.
