Where Is the North Star, and How Do You Find It?
Polaris, the North Star, sits almost due north in the Northern Hemisphere, close to the north celestial pole. You can find it by following the Big Dipper or Cassiopeia. It is not especially bright, but it barely moves while the other stars circle around it.
Quick answer
Polaris sits in the direction of north, very close to the north celestial pole (the point the Earth's axis points to). Its height above the horizon roughly matches your latitude, so the farther north you live, the higher it appears.
Two easy ways to find it
- Using the Big Dipper: take the two stars at the end of the Dipper's bowl, Dubhe and Merak, and extend the line about five times the gap between them. You land on Polaris. See the Big Dipper.
- Using Cassiopeia: on the opposite side of the pole, the W-shaped constellation points toward Polaris from its middle. See Cassiopeia.
A common mix-up
Polaris is not the brightest star in the sky. It is moderately bright, and Sirius outshines it by far. What makes it special is position, not brilliance.
Why it stays put
Because Earth's axis points almost straight at it, the sky seems to turn around Polaris during the night. Over thousands of years, precession, a slow wobble of the axis, will shift the pole toward other stars. Observers in most of the Southern Hemisphere cannot see Polaris and use other guides such as the Southern Cross.
Questions and answers
Is Polaris the brightest star in the sky?
No. It is only moderately bright. It is famous for its fixed position near the north celestial pole.
Can you see Polaris from the Southern Hemisphere?
Not from most southern locations, because it lies below the horizon. People there use other guides, like the Southern Cross.
